Subject: drm/i915/dsi: use a temp variable for referencing the gpio table
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b13d8e2888f60a18556844ed8958fd32bff1827c;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/dsi: use a temp variable for referencing the gpio table

The shorthand is easier. Also change the struct name. No functional
changes.
