[waffle] [RFC PATCH 0/3] Silence compiler warnings

[Emil Velikov]

Hi all,

The following three patches silences -Wunused-parameter warnings 
encountered on a Android 5 build.

Which prompted me - "How interesting is the build if we add -Wextra ?"
 - ~60 -Wunused-parameter warnings remaining.
 - 1 -Wsign-compare
 - and 212 -Woverride-init

The last one we're attempting to silence, yet the argument used seems to 
be clang specific (-Wno-initializer-overrides) and throws a warning.

Should we bother addressing those, or just leave -Wextra disabled ?

Cheers,
Emil

P.S. That's enough waffle + android nit-picking for now. I'm going to 
head over to drm and mesa :-)
