X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=459b81808f76f4a0e902e4988200373a627a57a8;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

gpio: kempld: use BIT() macro instead of shifting bits

Using the BIT() macro instead of shifting bits
makes the code less error prone and also more readable.
