The function HTSetConnectBwModeCallback() is only used in the file
in which it is defined, so has been changed to being of type 'static'.
Additionally the function is defined after it is used so a prototype
was included in the file. This prototype, in the middle of the file
has been removed and the function implementation moved so that it is
defined before it is used in the file.
This is a coding style change which should have no impact on runtime
code execution.

Clang generates a warning when it sees a logical not followed by a
conditional operator like ==, >, or < because it thinks that the logical
not should be applied to the whole statement:
drivers/staging/rtl8188eu/core/rtw_ieee80211.c:293:8: warning: logical
not is only applied to the left hand side of this comparison
[-Wlogical-not-parentheses]
It assumes the author might have made a mistake in their logic:
if (!a == b) -> if (!(a == b))
Sometimes that is the case; other times, it's just a super convoluted
way of saying 'if (a)' when b = 0:
if (!1 == 0) -> if (0 == 0) -> if (true)
Alternatively:
if (!1 == 0) -> if (!!1) -> if (1)
Simplify these comparisons so that Clang doesn't complain.
Clang warns when multiple pairs of parentheses are used for a single

it didn't happen.

Multiref support means that a compressed page could have
