staging: bcm2835-camera: Handle empty EOS buffers whilst streaming
The change to mapping V4L2 to MMAL buffers 1:1 didn't handle
the condition we get with raw pixel buffers (eg YUV and RGB)
direct from the camera's stills port. That sends the pixel buffer
and then an empty buffer with the EOS flag set. The EOS buffer
wasn't handled and returned an error up the stack.
Handle the condition correctly by returning it to the component
if streaming, or returning with an error if stopping streaming.

Before commit "staging: bcm2835-camera: Remove V4L2/MMAL buffer remapping"
there was a need to ensure that there were sufficient buffers supplied from
the user to cover those being sent to the VPU (always 1).
Now the buffers are linked 1:1 between MMAL and V4L2,
therefore there is no need for that check, and indeed it is wrong
as there is no need to submit all the buffers before starting streaming.

staging/most/video: set device_caps in struct video_device
Instead of filling in the struct v4l2_capability device_caps
field, fill in the struct video_device device_caps field.
That way the V4L2 core knows what the capabilities of the
video device are.

staging: erofs: don't check special inode layout
Currently, we will check if inode layout is compression or inline if
the inode is special in fill_inode(). Also set ->i_mapping->a_ops for
it. That is pointless since the both modes won't be set for special
inode when creating EROFS filesystem image. So, let's avoid it.

staging: erofs: return the error value if fill_inline_data() fails
We should consider the error returned by fill_inline_data() when filling
last page in fill_inode(). If not getting inode will be successful even
though last page is bad. That is illogical. Also change -EAGAIN to 0 in
fill_inline_data() to stand for successful filling.

staging: rtl8712: reduce stack usage, again
An earlier patch I sent reduced the stack usage enough to get
below the warning limit, and I could show this was safe, but with
GCC_PLUGIN_STRUCTLEAK_BYREF_ALL, it gets worse again because large stack
variables in the same function no longer overlap:
drivers/staging/rtl8712/rtl871x_ioctl_linux.c: In function 'translate_scan.isra.2':
drivers/staging/rtl8712/rtl871x_ioctl_linux.c:322:1: error: the frame size of 1200 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
Split out the largest two blocks in the affected function into two
separate functions and mark those noinline_for_stack.
