From: Dave Airlie Date: Fri, 29 Sep 2017 05:44:54 +0000 (+1000) Subject: amdgpu/dc: remove pointless returns in the i2caux constructor paths. (v2) X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b08c3ca4e90d03b3a120f4e60dba4b2b5e087433;p=openwrt%2Fstaging%2Fblogic.git amdgpu/dc: remove pointless returns in the i2caux constructor paths. (v2) There was lots of return true, and error checking that was never used in these paths. Just remove it all. v2: I missed one return true.
