staging: rtl8723bs: rework debug configuration handling

I ran into this warning during randconfig testing:

drivers/staging/rtl8723bs/os_dep/rtw_proc.c: In function 'rtw_adapter_proc_deinit':
drivers/staging/rtl8723bs/os_dep/rtw_proc.c:738:25: error: unused variable 'drv_proc' [-Werror=unused-variable]

drivers/staging/rtl8723bs/os_dep/rtw_proc.c:762:25: error: unused variable 'drv_proc' [-Werror=unused-variable]

The problem is that the code procfs code gets built even when CONFIG_PROC_FS
is disabled, but some functions are turned into empty stubs then. This
is easily addressed by adding an #ifdef around the definition of the
CONFIG_PROC_DEBUG macro.

However, I could not bear looking at the macro name that clashes with the
Kconfig name space, so I also renamed it to simply PROC_DEBUG, along with
the other rtl8723bs specific CONFIG_DEBUG_* macros that I renamed the same
way. This is consistent with how we handle the same checks in the non-staging
rtlwifi driver.

As the code path for !CONFIG_PROC_DEBUG had not been tested properly, it
turned out to be incorrect and requires adding 'static inline' annotations
for the stub handlers, and moving some variables around.

abstracted away. This makes the code easier to read. Also future

Driver currently uses the CONNECT_STATUS and DISCONNECT_STATUS as

When CMA was first introduced, its primary use was for DMA allocation
and the only way to get CMA memory was to call dma_alloc_coherent. This
put Ion in an awkward position since there was no device structure
readily available and setting one up messed up the coherency model.
These days, CMA can be allocated directly from the APIs. Switch to using
this model to avoid needing a dummy device. This also mitigates some of
the caching problems (e.g. dma_alloc_coherent only returning uncached
memory).

cma: Introduce cma_for_each_area

Frameworks (e.g. Ion) may want to iterate over each possible CMA area to
allow for enumeration. Introduce a function to allow a callback.

cma: Store a name in the cma structure

Frameworks that may want to enumerate CMA heaps (e.g. Ion) will find it
useful to have an explicit name attached to each region. Store the name
in each CMA structure.

Fifth set of IIO fixes for the 4.11 cycle.

As these are rather late in the cycle, they may sneak over into 4.12.
There is a fix for a regression caused by another fix (hid sensors
hardware seems to vary a lot in how various corner cases are handled).

* ad7303
  - fix channel description. Numeric values were being passed as characters
  presumably leading to garbage from the userspace interface.
* as3935
  - the write data macro was wrong so fix it.
* bmp280
  - incorrect handling of negative values as being unsigned broke humidity
  calculation.
* hid-sensor
  - Restore the poll and hysteresis values after resume as some hardware
  doesn't do it.
* stm32-trigger
  - buglet in reading the sampling frequency

staging: media/platform/bcm2835: remove gstreamer workaround

Gstreamer's v4l2src reacted poorly to certain outputs from the bcm2835
video driver's ioctl ops function vidioc_enum_framesizes, so a
workaround was created that could be activated by user input. This
workaround would replace the driver's ioctl ops struct with another,
similar struct--only with no function pointed to by
vidioc_enum_framesizes. With no response, gstreamer would attempt to
continue with some default settings that happened to work better.

However, this bug has been fixed in gstreamer since 2014, so we
shouldn't include this workaround in the stable version of the driver.
