[PATCH] drm/gma500: Fix direction check in psb_accel_2d_copy()

From: Denis Efremov
Date: Mon Jun 22 2020 - 16:45:57 EST


psb_accel_2d_copy() checks direction PSB_2D_COPYORDER_BR2TL twice.
Based on psb_accel_2d_copy_direction() results, PSB_2D_COPYORDER_TL2BR
should be checked instead in the second direction check.

Fixes: 4d8d096e9ae8 ("gma500: introduce the framebuffer support code")
