Subject: drm/i915: Invert the mask and val arguments in wa_add() and WA_REG()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cf4b0de6a3f6e1814c45206a8b175d09b265bb16;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Invert the mask and val arguments in wa_add() and WA_REG()

While trying to unify the order of those arguments throughout the
driver, Daniel noticed what we were inverting them in this part of the
code.
