Subject: [PATCH 2/6] staging: tidspbridge: drop const from custom mmu implementation
Date: Wed, 24 Oct 2012 17:09:16 -0500 [thread overview]
Message-ID: <1351116560-6918-3-git-send-email-omar.ramirez@copitl.com> (raw)
In-Reply-To: <1351116560-6918-1-git-send-email-omar.ramirez@copitl.com>
Custom mmu functions receive a 'const void __iomem *', all the
callers pass a 'void __iomem *', so drop the const to fix the
warnings like:
warning: passing argument 2 of '__raw_writel' discards qualifiers from pointer target type
../io.h:88: note: expected 'volatile void *' but argument is of type 'const void *'
Signed-off-by: Omar Ramirez Luna <omar.ramirez@copitl.com>

Intended for 3.7 due to code changes during rc1.
