X-Git-Tag: v2.6.34-rc4~88^2~2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9e5786bd14cb9ffe29ebe66d41cedf03311b0d30;p=pandora-kernel.git drm/radeon/kms: add sanity check to wptr. If we resume in a bad way, we'll get 0xffffffff in wptr, and then oops with no console. This just adds a sanity check so that we can avoid the oops and hopefully get more details out of people's systems. Signed-off-by: Dave Airlie --- Reading git-diff-tree failed
