-Subject: [PATCH] drm/amd/display: fix divide error in plane scale calcs
-
-dm_get_plane_scale doesn't take into account plane scaled size equal to
-zero, leading to a kernel oops for division by zero. Fix by setting
-out-scale size as zero when the dst size is zero, similar to what is
-done by drm_calc_scale(). This issue started with the introduction of
-cursor ovelay mode that uses this function to assess cursor mode changes
-via dm_crtc_get_cursor_mode() before checking plane state.
-
-Fixes: 1b04dcca4fb1 ("drm/amd/display: Introduce overlay cursor mode")
-Link: https://gitlab.freedesktop.org/drm/amd/-/issues/3729
