From: Lionel Landwerlin Date: Sat, 19 Oct 2019 21:46:47 +0000 (+0300) Subject: drm/i915/perf: fix oa config reconfiguration X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8814c6d01f7e82e6be70ac04d8bca0fc90757418;p=openwrt%2Fstaging%2Fblogic.git drm/i915/perf: fix oa config reconfiguration The current logic just reapplies the same configuration already stored into stream->oa_config instead of the newly selected one.
