staging: vchiq_core: fix quoted strings split across lines

Quoted strings should not be split across lines. As put it in [1]:
"never break user-visible strings such as printk messages because that
breaks the ability to grep for them."

While at it, fix the alignment of the arguments in the sentence.

Note: this introduce a checkpatch CHECK: line length of 123 exceeds 100
columns, as the line now is:

 vchiq_loud_error("%d: service %d (%c%c%c%c) version mismatch - local (%d, min %d) vs. remote (%d, min %d)",

But now the string is grep-able and the whole function call more
clear.

staging: r8188eu: Use a Mutex instead of a binary Semaphore

Use a Mutex instead of a binary Semaphore for the purpose of enforcing
mutual exclusive access to the "pwrctrl_priv" structure.

Mutexes are sleeping locks similar to Semaphores with a 'count' of one
(like binary Semaphores), however they have a simpler interface, more
efficient performance, and additional constraints.

There is no change in the logic of the new code; however it is more
simple because it gets rid of four unnecessary wrappers:
_init_pwrlock(), _enter_pwrlock(),_exit_pwrlock(), _rtw_down_sema().

Actually, there is a change in the state in which the code waits for
acquiring locks, because it makes it in an uninterruptible state
(instead the old code used down_interruptibe()). Interruptible
waits are neither required nor wanted in this driver.

Tested with ASUSTek Computer, Inc. Realtek 8188EUS [USB-N10 Nano].

staging: r8188eu: Remove redundant 'if' statement

Remove the redundant first 'if' statement of two identical ones.

In rtw_cmd_thread() there are two identical 'if' statement, one
immediately after the other. They check whether or not the device is
removed or the driver is stopped and, if true, they break a 'while'
loop.

The only noteworthy context difference is that the second statement is
within a block labelled "_next". The code has a 'goto' to the "_next"
label so that the checking is performed each time the above directive
is encountered. Instead, the first 'if' is before the "_next" label.

One of the two must be removed and that it must be the one before the
label because "bSurpriseRemoved" as well as "bDriverStopped" may be
changed asynchronously by other code of the driver and so they should be
checked at each jump to "_next".

staging: r8188eu: Use completions for signaling start / end kthread

rtw_cmd_thread() "up(s)" a semaphore twice, first to notify callers when
its execution is started and then to notify when it is about to end.

It makes the same semaphore go "up" twice in the same thread. This
construct makes Smatch to warn of duplicate "up(s)".

This thread uses interruptible semaphores where instead completions are
more suitable. For this purpose it calls an helper (_rtw_down_sema())
that returns values that are never checked. It may lead to bugs.

To address the above-mentioned issues, use two completions variables
instead of semaphores. Use the uninterruptible versions of
wake_for_completion*() because the interruptible / killable versions are

staging: r8188eu: remove two checks that are always false

Commit aefb1fc5c185 ("staging: r8188eu: odm BoardType is never set")
clarified that the odm board type is always 0.

The CheckCondition functions extract the board type from the hex
parameter and stores it in _board. For _board == 0,
(_board == cond) && cond != 0x00 is always false. Remove the checks.
