This patch makes locking in visorchannel_signalempty statically
deterministic.
As a result this patch fixes the sparse warning:
Context imbalance in 'visorchannel_signalempty' - different lock
contexts for basic block.
The logic of the locking code doesn't change but the layout of the
original code is "frowned upon"
according to mails on sparse context checking.
Refactoring removes the warning and makes the code more readable.

I've left out the downstream HDMI audio driver from the "to be
imported" section, as we'll want to handle it natively in vc4. The
downstream kernel will likely continue to use that driver for a while
due to using the interim "vc4 firmware KMS" mode while vc4 gets its
featureset (such as HDMI audio!) completed.
I've also left out VC-CMA, which appears to be about having Linux
manage a CMA area that the firmware gets to make allocations out of.
I'm not clear on if this is useful (the firmware's need for memory
drops massively with vc4 present, and may drop even more depending on
how we resolve dmabuf handling for camera and video decode)

uninitialized pointer into 'strchr', which can cause a kernel page fault

The rtllib_rx_extract_addr() is supposed to set up the mac addresses
for four possible cases, based on two bits of input data. For
some reason, gcc decides that it's possible that none of the these
four cases apply and the addresses remain uninitialized:
drivers/staging/rtl8192e/rtllib_rx.c: In function ‘rtllib_rx_InfraAdhoc’:
include/linux/etherdevice.h:316:61: error: ‘*((void *)&dst+4)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/staging/rtl8192e/rtllib_rx.c:1318:5: note: ‘*((void *)&dst+4)’ was declared here
ded from /git/arm-soc/drivers/staging/rtl8192e/rtllib_rx.c:40:0:
include/linux/etherdevice.h:316:36: error: ‘dst’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/staging/rtl8192e/rtllib_rx.c:1318:5: note: ‘dst’ was declared here
This warning is clearly nonsense, but changing the last case into
'default' makes it obvious to the compiler too, which avoids the
warning and probably leads to better object code too.
As the same warning appears in other files that have the exact
same code, I'm fixing it in both rtl8192e and rtl8192u, even
though I did not observe it for the latter.
