From: Aurabindo Pillai Date: Thu, 25 Sep 2025 14:23:59 +0000 (-0400) Subject: drm/amd/display: use GFP_NOWAIT for allocation in interrupt handler X-Git-Tag: v6.18-rc3~16^2~3^2 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=72a1eb3cf573ab957ae412f0efb0cf6ff0876234;p=thirdparty%2Flinux.git drm/amd/display: use GFP_NOWAIT for allocation in interrupt handler schedule_dc_vmin_vmax() is called by dm_crtc_high_irq(). Hence, we cannot have the former sleep. Use GFP_NOWAIT for allocation in this function.
