From 2b76f5be7c2778ee2f6bacddc19248f6a4a467a0 Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Wed, 19 Dec 2018 15:16:41 +0100 Subject: [PATCH] drm/etnaviv: initialize idle mask before querying the HW db If there is a match in the HW DB, the function is left early, before inititalizing the idle mask. Fix this by doing the init earlier, as only old GPUs, not present in the HW DB need a different idle mask.
