From 1ad759df6a6f873a7cc116b2e88759e790a7f04f Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Mon, 2 Jan 2023 11:02:00 +0100 Subject: [PATCH] drm/msm/adreno: Make adreno quirks not overwrite each other commit 13ef096e342b00e30b95a90c6c13eee1f0bec4c5 upstream. So far the adreno quirks have all been assigned with an OR operator, which is problematic, because they were assigned consecutive integer values, which makes checking them with an AND operator kind of no bueno.. Switch to using BIT(n) so that only the quirks that the programmer chose are taken into account when evaluating info->quirks & ADRENO_QUIRK_...
