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.

Driver SDIO code uses helper functions to do IO to the SDIO
device. Current helpers handle IO of a single byte as well as
multi-byte. Driver predominately uses single byte IO. If the
common case is made simple it simplifies the whole driver. The common
case can be made simple by splitting the multi-byte and single byte
calls into separate functions, i.e 4 functions in total, read single
byte, read multi-byte, write single byte, write multi-byte.
Also, we need to handle the debug code. Currently debug calls after
read/write fail access the IO buffer. This buffer, at best, does not hold
useful data on the error path, at worst is uninitialized and holds
garbage.
Split read/write helper functions into two functions each, one for
single byte IO and one for multi-byte IO. Fix all call sites. Do not
change the program logic.

staging: ks7010: move hw info into dev private data
Currently driver uses a hardware information struct description to
group some SDIO related functionality (work, work queue, sdio private
data pointer). This structure is then embedded in the device private
data structure. Having nested structures described in different header
files means that to view the device private data programmers must open
two header files. This structure could be embedded anonymously in the
device private data and achieve the same result (grouping of function
specific to SDIO) without the need to open multiple headers. However,
the SDIO private data structure already has various different data and
pointers, adding the embedded structure adds little extra meaning and
lengthens all the dereferences throughout the driver, often meaning
addition line breaks and braces. We can increase readability and
reduce code complexity by moving the hardware information data and
pointers to directly be within the device private data structure
description.
While preparing for this refactoring it was noted that the identifier
currently used for the delayed work is 'rw_wq', this is confusing
since the 'wq' suffix typically means 'work queue'. This identifier
would be more meaningful if it used the suffix 'dwork' as does the
declaration of queue_delayed_work() (include/linux/workqueue.h).
The identifier for the work queue is currently 'ks7010sdio_wq'. This
identifier can be shortened without loss of meaning because there is
only one work queue within the driver. Identifier 'wq' is typical
within in-tree driver code and aptly describes the pointer.
Current pointer to the SDIO private data is identified by 'sdio_card',
this is sufficiently meaningful from within the hw_info structure but
once the hw_info_t structure is removed the pointer would be better to
have a prefix appended to it to retain the prior level of meaning.
Move members from struct hw_info_t to struct ks_wlan_private.
Rename identifiers;
struct delayed_work pointer 'rw_wq' to 'rw_dwork'.
struct workqueue_struct pointer 'ks7010sdio_wq' to 'wq'.
struct ks_sdio_card pointer 'sdio_card' to 'ks_sdio_card'.
Remove structure description hw_info_t. Fix init/destroy calls. Fix
all call sites, SDIO private data access calls, and queuing calls.

staging: ks7010: move tasklet_struct to ks_wlan_private
Currently a pointer to the tasklet_struct used for bottom half
processing on the receive path is within the hw_info_t structure. This
structure is then embedded in the device private data
structure. Having the tasklet_struct nested does not add meaning to
the device private data, device private data already (and typically)
has various data relating to the device, there is no real need to
separate the tasklet_struct to a SDIO specific structure. While not
adding allot of extra meaning having the nested structure means the
programmer must open two header files to read the description of the
device private data, the code would be easier to read if the device
private data struct description was not spread over two files.
Move tasklet_struct out of sdio header file and into the device
private data structure description.

staging: rtl8723bs: Fix indenting problems in core/rtw_odm.c

Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
The indenting problems were fixed with white-space changes. The error at
line 1595 was the result of an off-by-one error in a for loop. The error
at line 4969 was not fixed as that code lies inside a block of code that
only is needed for 5G channels. This chip only works at 2.4 GHz.

The first two are fixed with white-space changes. The third is fixed by
restricting cam_id to be less than 32.
