afc023da53 staging: mmal-vchiq: Fix incorrect static vchiq_instance. 
For some reason lost in history function vchiq_mmal_init used
a static variable for storing the vchiq_instance.
This value is retrieved from vchiq per instance, so worked fine
until you try to call vchiq_mmal_init multiple times concurrently
when things then go wrong. This seemed to happen quite frequently
if using the cutdown firmware (no MMAL or VCSM services running)
as the vchiq_connect then failed, and one or other vchiq_shutdown
was working on an invalid handle.

Remove the static so that each caller gets a unique vchiq_instance.

7f8d698ffb staging: rtl8188eu: convert pr_info call to dev_err call ODM_RAStateCheck 
Introduce logic to extract struct device pointer from passed in struct
odm_dm_struct pointer argument, and use this to call dev_err instead of
pr_info. As this is an error state if this line is reached, this is not
just information. Also, this is a driver, so dev_err is more
appropriate.

a75d6a3279 staging: rtl8188eu: remove ASSERT and ODM_RT_ASSERT macros 
Remove the ASSERT and ODM_RT_ASSERT macros from include/odm_debug.h
as they are unnecessary.

ASSERT does nothing, compiling to a single empty statement.
ODM_RT_ASSERT is used in only one place, in the ODM_RAStateCheck
function with hal/odm.c - it seems to have been intended as an
assertion of some kind, but given it is always called with false
here, there is little point in it not just being a pr_info() call.

Also, the lines relating to the file, function and line number are
not needed as the pr_info() with the function name and error message
is sufficient should anyone wish to track down this error at a source
level, within what is currently a relatively small function.

3c8c577fd2 staging: rtl8723bs: refactor to reduce indents 
Reduce the number of indents in rtw_wlan_util.c file by refactoring the
code.

Moved the part of code that rearranged ac paramaters in the function
WMMOnAssocResp to a separate function named sort_wmm_ac_params. It takes
both the array of ac params and their indexes as arguments and sorts them.
Has return type void.

Moved the part of code that checked IE for realtek vendor in the
function check_assoc_AP to a separate function named
get_realtek_assoc_AP_vender. It takes a struct ndis_80211_var_ie * as an
argument and returns u32 realtek vendor.

1b4c0f3bbd staging: rtl8723bs: rename get_ra() due to global symbol collision 
Turns out that powerpc already has a get_ra() function, which conflicts
with this staging driver's inlined function (which is just picking a
byte out of an array for some odd reason), so rename it to fix the
powerpc build as that's the more important thing here.

Oddly, it's not catching all of the "set but not used" variables in this
switch statement.  Fix it up just removing the storage of the values
read.  Leave the read from the hardware as odds are it is required in
order to keep it working properly as I do not have the hardware to test
with.

I bet the whole case can be removed, but that will have to wait until
later...

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.

16b1b3c822 staging: rtl8723bs: remove duplicate names for _rtw_read32() 
_rtw_read32() is redefined as rtw_read32() and PlatformEFIORead4Byte().
Because rtw_read32() is the only name used in the driver, remove the
duplicate definitions and rename the function from _rtw_read32() to
rtw_read32()

4c51210461 staging: vchiq_core: introduce parse_message 
The function parse_rx_slots is very longer. So move at least the message
parsing into a separate function to improve readability. In good case
the function returns the message payload length which is necessary to
move to the next message.
