+Subject: drm/radeon: fix ATPX detection on non-VGA GPUs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Alex Deucher <alexdeucher@gmail.com>
+
+commit e9a4099a59cc598a44006059dd775c25e422b772 upstream.
+
+Some newer PX laptops have the pci device class
+set to DISPLAY_OTHER rather than DISPLAY_VGA.  This
+properly detects ATPX on those laptops.
+
+Based on a patch from: Pali Rohár <pali.rohar@gmail.com>
