Joe Perches d4e25108bb staging: wilc1000: Neaten refresh_scan - remove always 1 argument
All uses of refresh_scan() have a constant 1 as the second argument.
Remove it and neaten the function declaration.

Miscellanea:

o Remove overly deep indentation by using continue;
o Remove unnecessary test of the address of a static array as it's
  always non-zero
o Rename and use proper type for the first void * argument as it's
  always the struct wilc_priv *
o Move variables into loop where used

Johannes Berg d58ff35122 networking: make skb_push & __skb_push return void pointers
It seems like a historic accident that these return unsigned char *,
and in many places that means casts are required, more often than not.

Make these functions return void * and remove all the casts across
the tree, adding a (u8 *) cast only where the unsigned char pointer
was used directly, all done with the following spatch:

    @@
    expression SKB, LEN;
    typedef u8;
    identifier fn = { skb_push, __skb_push, skb_push_rcsum };
    @@
    - *(fn(SKB, LEN))

Note that the last part there converts from push(...)[0] to the

Aditya Shankar 46949b4856 staging: wilc1000: New cfg packet format in handle_set_wfi_drv_handler
Change the config packet format used in handle_set_wfi_drv_handler()
to align the host driver with the new format used in the wilc firmware.

The change updates the format in which the host driver provides the
firmware with the drv_handler index and also uses two new
fields viz. "mode" and 'name" in the config packet along with this index
to directly provide details about the interface and its mode to the
firmware instead of having multiple if-else statements in the host driver
to decide which interface to configure.

This change requires users to move to the newer version of the wilc
firmware(14.02 or higher) available on the vendor tree on github or on the
linux-firmware project. The existing firmware files on the linux-firmware
project are very old and best not used.

This is not the first attempt to address this problem:
    https://lkml.org/lkml/2017/3/7/808

First, the current code works because the final use of the
ht_capa values (in host_interface.c: WILC_HostIf_PackStaParam) packs them
into a buffer in little-endian format. Since this matches the byte-order of
struct ieee80211_ht_cap, all is seemingly well.

What the current code does not do, and what these warnings expose, is
clearly communicate what the fields in struct add_sta_param
represent -- values with a specific (little endian) byte order.
This will lead to problems if the values are ever actually used by the
host, and that host is not little endian.

The proposed change addresses this by embedding a
struct ieee80211_ht_cap into struct add_sta_param.  When the values
are later packed out, the newly embedded struct is copied directly
into the outbound buffer.  All 16 and 32 bit types are treated as
little endian and marked as such.  Future use of the values by the
host would still require conversion, or sparse would flag them again.

The following items are required for this to be correct:
    1.  The data is not currently used by the host.
    2.  struct ieee80211_ht_cap is packed.
    3.  The packing of the fields matches the order in
        struct ieee80211_ht_cap.

This is similar, I believe, to how the same data is handled in
marvell/mwifiex/11n.c.

Test-compiled/loaded against staging-next on x86_64
Test-compiled against staging-next for ARM.
Applied/built against staging-testing.

Testing consists of compilation for the above trees/targets, and a
sparse check, no functional testing.

Linus Torvalds c6a677c6f3 Staging/IIO patches for 4.12-rc1
Here is the big staging tree update for 4.12-rc1.  And it's a big one,
 adding about 350k new lines of crap^Wcode, mostly all in a big dump of
 media drivers from Intel.  But there's other new drivers in here as
 well, yet-another-wifi driver, new IIO drivers, and a new crypto
 accelerator.  We also deleted a bunch of stuff, mostly in patch
 cleanups, but also the Android ION code has shrunk a lot, and the
 Android low memory killer driver was finally deleted, much to the
 celebration of the -mm developers.
 
 All of these have been in linux-next with a few build issues that will

 after this gets merged.

Aditya Shankar 0e490657c7 staging: wilc1000: Fix problem with wrong vif index
The vif->idx value is always 0 for two interfaces.

wl->vif_num = 0;

loop {
     ...

     vif->idx = wl->vif_num;
     ...
     wl->vif_num = i;
      ....
     i++;
     ...
}

At present, vif->idx is assigned the value of wl->vif_num
at the beginning of this block and device is initialized
based on this index value.
In the next iteration, wl->vif_num is still 0 as it is only updated
later but gets assigned to vif->idx in the beginning. This causes problems
later when we try to reference a particular interface and also while
configuring the firmware.

This patch moves the assignment to vif->idx from the beginning
of the block to after wl->vif_num is updated with latest value of i.

Colin Ian King 6e9f6b54c5 staging: wilc1000: fix incorrect copy of pmkid data
The pmkid data is meant be be copied to the previous item in the
pmkidlist, however the code is just copying the data to itself because
the src index into pmkidlist is the same as the dst index into pmkidlist.
Fix this with i + 1 instead of i.

by using the following coccinelle script.
