From: Colin Ian King Date: Thu, 1 Aug 2019 11:01:45 +0000 (+0100) Subject: drm/amdgpu: fix unsigned variable instance compared to less than zero X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ac4bf4a1ebce7554628db89498ec49054c7bcdba;p=openwrt%2Fstaging%2Fblogic.git drm/amdgpu: fix unsigned variable instance compared to less than zero Currenly the error check on variable instance is always false because it is a uint32_t type and this is never less than zero. Fix this by making it an int type.
