ASoC: soc-card: Create jack kcontrol without pins
snd_soc_card_jack_new() allowed to create jack kcontrol without pins,
but did not create kcontrols. The jack would not have kcontrols if pins
were not going to be added.

This renames the old snd_soc_card_jack_new() to
snd_soc_card_jack_new_pins() for use when pins are provided or will be
added later. The new snd_soc_card_jack_new() appropriately creates a
jack for use without pins and adds a kcontrol.

Linus Torvalds dfdc1de642 Staging driver update for 5.18-rc1
Here is the big set of staging driver updates for 5.18-rc1.
 
 Loads of tiny cleanups for almost all staging drivers in here, nothing
 major at all.  Highlights include:
 	- remove the ashmem Android driver.  It is long-dead and if
 	  there are any legacy userspace applications still using it,
 	  the Android kernel images will maintain it, the community
 	  shouldn't care about it anymore
 	- wfx wifi driver major cleanups.  Should be ready to merge out
 	  of staging soon, and will coordinate with the wifi maintainers
 	  after -rc1 is out
 	- major cleanups and unwinding of the layers of the r8188eu
 	  driver.  It's amazing just how many unneeded layers of
 	  abstraction is in there, just when we think it's done, another
 	  is found...
 	- lots of tiny coding style cleanups in many other staging
 	  drivers.
 
 There will be merge conflict with a fbtft change and the spi driver
 changes in your tree, but it's pretty obvious what to do (the function
 shouldn't return anything.)
 
 All have been in linux-next for a while with no reported problems.

Linus Torvalds 50560ce6a0 Kbuild -std=gnu11 updates for v5.18
Linus pointed out the benefits of C99 some years ago, especially variable
 declarations in loops [1]. At that time, we were not ready for the
 migration due to old compilers.
 
 Recently, Jakob Koschel reported a bug in list_for_each_entry(), which
 leaks the invalid pointer out of the loop [2]. In the discussion, we
 agreed that the time had come. Now that GCC 5.1 is the minimum compiler
 version, there is nothing to prevent us from going to -std=gnu99, or even
 straight to -std=gnu11.
 
 Discussions for a better list iterator implementation are ongoing, but
 this patch set must land first.

building with -Wextra for c99 or higher, but not for c89. Since

Jiasheng Jiang 2e81948177 staging: greybus: audio: Check null pointer
As the possible alloc failure of devm_kcalloc(), it could return null
pointer.
Therefore, 'strings' should be checked and return NULL if alloc fails to
prevent the dereference of the NULL pointer.
Also, the caller should also deal with the return value of the
gb_generate_enum_strings() and return -ENOMEM if returns NULL.
Moreover, because the memory allocated with devm_kzalloc() will be
freed automatically when the last reference to the device is dropped,
the 'gbe' in gbaudio_tplg_create_enum_kctl() and
gbaudio_tplg_create_enum_ctl() do not need to free manually.
But the 'control' in gbaudio_tplg_create_widget() and
gbaudio_tplg_process_kcontrols() has a specially error handle to
cleanup.
So it should be better to cleanup 'control' when fails.

Uwe Kleine-König fc7a6209d5 bus: Make remove callback return void
The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.

This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.

With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

Linus Torvalds c932ed0adb TTY / Serial patches for 5.14-rc1
Here is the big set of tty and serial driver patches for 5.14-rc1.
 
 A bit more than normal, but nothing major, lots of cleanups.  Highlights
 are:
 	- lots of tty api cleanups and mxser driver cleanups from Jiri
 	- build warning fixes
 	- various serial driver updates
 	- coding style cleanups
 	- various tty driver minor fixes and updates
 	- removal of broken and disable r3964 line discipline (finally!)
 
 All of these have been in linux-next for a while with no reported
 issues.

In the previous patch, we introduced tty_get_char_size() and
tty_get_frame_size() for computing character and frame sizes,
respectively. Here, we make use of them in various tty drivers where
applicable.

Rajat Asthana 9a032e3f7e staging: greybus: audio: Fix sparse warning.
Sparse complains that:
   warning: restricted send_ctl_elem_iface_t degrades to integer.

I have looked at this code, and the code is fine as-is. Normally we
would frown on using the __force directive to silence Sparse warnings
but in this case it's fine. Case statements can't be made into __bitwise
types. We also can't change the type of "ctl->iface" either because that
is part of the user space API.

So just add a (__force int) to make the warning go away.

Johan Hovold d38be70245 staging: greybus: uart: clean up TIOCGSERIAL
TIOCSSERIAL is a horrid, underspecified, legacy interface which for most
serial devices is only useful for setting the close_delay and
closing_wait parameters.

The xmit_fifo_size parameter could be used to set the hardware transmit
fifo size of a legacy UART when it could not be detected, but the
interface is limited to eight bits and should be left unset when not
used.

Similarly, baud_base could be used to set the UART base clock when it
could not be detected but might as well be left unset when it is not
known.

The type parameter could be used to set the UART type, but is
better left unspecified (type unknown) when it isn't used.

Note that some applications have historically expected TIOCGSERIAL to be
implemented, but judging from the Debian sources, the port type not
being PORT_UNKNOWN is only used to check for the existence of legacy
serial ports (ttySn). Notably USB serial drivers like ftdi_sio have been
using PORT_UNKNOWN for twenty years without any problems.

Drop the bogus values provided by the greybus implementation.

TIOCSSERIAL is a horrid, underspecified, legacy interface which for most

closing_wait parameters.

A non-privileged user has only ever been able to set the since long
deprecated ASYNC_SPD flags and trying to change any other *supported*
feature should result in -EPERM being returned. Setting the current
values for any supported features should return success.

Fix the greybus implementation which instead indicated that the
TIOCSSERIAL ioctl was not even implemented when a non-privileged user
set the current values.

Alexandru Ardelean 33a23423ca
staging: greybus: spilib: use 'spi_delay_to_ns' for getting xfer delay
The intent is the removal of the 'delay_usecs' field from the
spi_transfer struct, as there is a 'delay' field that does the same
thing.

The spi_delay_to_ns() can be used to get the transfer delay. It works by
using the 'delay_usecs' field first (if it is non-zero), and finally
uses the 'delay' field.

Since the 'delay_usecs' field is going away, this change makes use of the
spi_delay_to_ns() function. This also means dividing the return value of
the function by 1000, to convert it to microseconds.
To prevent any potential faults when converting to microseconds and since
the result of spi_delay_to_ns() is int, the delay is being computed in 32
bits and then clamped between 0 & U16_MAX.

Kumar Kartikeya Dwivedi a66111446d staging: greybus: Switch from strlcpy to strscpy
strlcpy is marked as deprecated in Documentation/process/deprecated.rst,
and there is no functional difference when the caller expects truncation
(when not checking the return value). strscpy is relatively better as it
also avoids scanning the whole source string.

This silences the related checkpatch warnings from:
