X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b1814a1def0564a2a1d3be7fa5bf7243ff899a28;p=openwrt%2Fstaging%2Fblogic.git drm/amd/powerplay: don't add invalid voltage. if atomctrl_get_voltage_evv_on_sclk_ai returns non zero (fail) in the expansion of the PP_ASSERT_WITH_CODE macro the continue will actually do nothing, So invalid voltage will be added to ppbable.
