From: Kevin Wang Date: Tue, 4 Jun 2019 09:38:42 +0000 (+0800) Subject: drm/amd/powerplay: remove smu callback funciton get_mclk(get_sclk) X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=576851345b677b28617217f5d97920f62eab471e;p=openwrt%2Fstaging%2Fblogic.git drm/amd/powerplay: remove smu callback funciton get_mclk(get_sclk) remove smu callback: get_mclk, get_sclk. because the function smu_get_dpm_freq_range has the same function.
