In a bus remove function the passed device is always valid, so there is
no need to check for it being NULL.
(Side note: The check for port being non-NULL is broken anyhow, because
to_usb_serial_port() is a wrapper around container_of() for a member that is
not the first one. So port can hardly become NULL.)

Clear the RTS bits of the flow-control request before determining the
new value when updating the settings.
Signed-off-by: Johan Hovold <johan@kernel.org>
Clearing TIOCM_RTS should always deassert RTS and setting the same bit
should enable auto-RTS if hardware flow control is enabled.
This allows user space to throttle input directly at the source also
when hardware-assisted flow control is enabled and makes dtr_rts()
always deassert both lines during close (when HUPCL is set).
Signed-off-by: Johan Hovold <johan@kernel.org>
Shorten the flow-control debug message by abbreviating the field names
and reducing the value width to two characters. The latter improves

The vendor request used to set the flow-control settings also sets the
state of the modem-control lines.
Add state variables to keep track of the modem-control lines to avoid
always asserting the lines whenever the flow-control settings are
updated.
This specifically also avoids asserting DTR/RTS when opening a port with
the line speed set to B0.

The CP210X_SET_MHS request cannot be used to control RTS when hardware
flow control (auto-RTS) is enabled and instead returns an error which is
currently logged as:
cp210x ttyUSB0: failed set request 0x7 status: -32
when opening and closing a port (and on TIOCMSET requests).
Add a crtscts flag to keep track of the hardware flow-control setting
and use it to suppress any request to change RTS when auto-RTS is
enabled.
Note that RTS is still deasserted when disabling the UART as part of
close.

Add support for MaxLinear/Exar USB to Serial converters. This driver
only supports XR21V141X series but it can be extended to other series
from Exar as well in future.
This driver is inspired from the initial one submitted by Patong Yang:
https://lore.kernel.org/r/20180404070634.nhspvmxcjwfgjkcv@advantechmxl-desktop
While the initial driver was a custom tty USB driver exposing whole
new serial interface ttyXRUSBn, this version is completely based on USB
serial core thus exposing the interfaces as ttyUSBn. This will avoid
the overhead of exposing a new USB serial interface which the userspace
tools are unaware of.
The Exar XR21V141X can be used in either ACM mode using the cdc-acm
driver or in "custom driver" mode in which further features such as
hardware and software flow control, GPIO control and in-band line-status
reporting are available.
In ACM mode the device always enables RTS/CTS flow control, something
which could prevent transmission in case the CTS input isn't wired up
corrently.
A follow-on patch will prevent cdc_acm from binding whenever this driver
is enabled.

At least CP2102 requires the XON/XOFF limits to be initialised in order
for software input flow control (IXOFF) to work. Specifically, XOFF is
never sent if the XOFF limit is left at its default value of zero.
Set the limits so that input is throttled when the FIFO free level drops
below 128 bytes and restarted when the FIFO fill level drops below 128
bytes.
Note that the threshold values have been chosen so that they can be used
also with CP2105 which has the smallest FIFO of the currently supported
device types (288 byte for the SCI port). If needed the limits can be
made device specific later.

When data is transmitted between two serial ports, the phenomenon of
data loss often occurs. The two kinds of flow control commonly used in
serial communication are hardware flow control and software flow
control.
In serial communication, If you only use RX/TX/GND Pins, you can't do
hardware flow. So we often used software flow control and prevent data
loss. The user sets the software flow control through the application
program, and the application program sets the software flow control mode
for the serial port chip through the driver.
For the cp210 serial port chip, its driver lacks the software flow
control setting code, so the user cannot set the software flow control
function through the application program. This adds the missing software
flow control.

Here are some small staging driver fixes for 5.11-rc3. Nothing major,
just resolving some reported issues:
- cleanup some remaining mentions of the ION drivers that were
removed in 5.11-rc1
- comedi driver bugfix
- 2 error path memory leak fixes
All have been in linux-next for a while with no reported issues.
