From 03286f948065d68194f5654373a9017a484d364a Mon Sep 17 00:00:00 2001 From: Lucas De Marchi Date: Fri, 30 Jun 2023 13:35:08 -0700 Subject: [PATCH] drm/i915/gt: Remove bogus comment on IVB_FBC_RT_BASE_UPPER The comment on the parameter being 0 to avoid the read back doesn't apply as this is not a call to wa_add(), but rather to wa_write_clr_set(). So, this register is actually checked and it's according to the Bspec that the register is RW, not RO.
