From: Omar Ramirez Luna <omar.l...@linaro.org>
This should get rid of warnings of the type:
warning: passing argument 1 of '' discards qualifiers from pointer target type
note: expected 'void *' but argument is of type 'const void *'
Signed-off-by: Omar Ramirez Luna <omar.rami...@copitl.com>

Intended for 3.7 due to code changes during rc1.
