From: Deepak Saxena Date: Mon, 5 Dec 2005 10:54:59 +0000 (+0000) Subject: [ARM] 3191/1: Mark I/O pointer as const in __raw_reads[bwl] X-Git-Tag: v2.6.15-rc6~103^2~3 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a0d95af5c28666155ad4c85a63a5065436ae1d79;p=linux-2.6 [ARM] 3191/1: Mark I/O pointer as const in __raw_reads[bwl] Patch from Deepak Saxena Mark the ioremap'd cookie/pointer in said functions as const since we should not be actualy touching the data. This fixes a slew of compile warnings on IXP4xx as our reads[bwl] already mark this parameter as const.
