Subject: drm: fix minor number range calculation
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=24f400326793341b005546d6ef82770f8d30d092;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm: fix minor number range calculation

Currently, both ranges overlap. Fix the limits so both ranges are mutually
exclusive. Also use the occasion to convert whitespaces to tabs.
