From 9de43e79c10149d29c77ff2c3dae048d1db9cbce Mon Sep 17 00:00:00 2001 From: Jordan Crouse Date: Thu, 1 Feb 2018 12:15:17 -0700 Subject: [PATCH] drm/msm/adreno: Use generic function to load firmware to a buffer object Move a5xx specific code to load firmware into a buffer object to the generic Adreno code. This will come in useful for future targets.
