Subject: sh: Kill off volatile silliness in sq_flush_range().
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b05d1865b46ea72c66ba082598ba370582bb590e;p=openwrt%2Fstaging%2Fblogic.git

sh: Kill off volatile silliness in sq_flush_range().

  CC      arch/sh/kernel/cpu/sh4/sq.o
arch/sh/kernel/cpu/sh4/sq.c: In function 'sq_flush_range':
arch/sh/kernel/cpu/sh4/sq.c:65: warning: passing argument 1 of 'prefetch' discards qualifiers from pointer target type

This didn't actually need to be volatile in the first place, so just
kill off the qualifier entirely.
