[B.A.T.M.A.N.] [PATCH v2 0/4] batman-adv: cleanups patches for Linux 4.12

[Sven Eckelmann]

[-- Attachment #1: Type: text/plain, Size: 1410 bytes --]

Hi,

here is the second version of cleanup patches. It addresses a couple of new
checks from checkpatch.pl:

 * CHECK: Macro argument reuse '%s' - possible side-effects?
 * CHECK: Unbalanced braces around else statement

The last check currently creates a lot of false positives but a fix for it was
already submitted to Andrew Morton (+ accepted).
 
It also contains a patch which converts the preprocessor blocks in
multicast.c to simple inline checks. The compiler can directly take care of
removing the unused code when some CONFIG_* option disabled.


changes in v2:

 * rebased on top of master
 * split "Fix possible side-effects in macros" in two patches
 * converted BATADV_PRINT_VID to an inline function

Kind regards,
	Sven

[B.A.T.M.A.N.] [PATCH v2 1/4] batman-adv: Remove preprocessor checks in multicast.c

[Sven Eckelmann]

It is not necessary to disable these code sections in case other kernel
features are disabled. Instead the IS_ENABLED tests can be added directly
in the code and the compiler can remove the unnecessary code parts during
its optimization run.
