Subject: mtdchar: Register the full range of minor numbers
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dad0db318b391ddb9845ac5e52044f921219bf69;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

mtdchar: Register the full range of minor numbers

register_chrdev() registers minor numbers up to 255, but we can now
potentially have much larger numbers.
