Subject: staging: sm750fb: use BIT macro for POWER_MODE_CTRL single-bit fields
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=776980cf0f8cd3c8e5863ec92bccb8e670e3efa1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

staging: sm750fb: use BIT macro for POWER_MODE_CTRL single-bit fields

Replace complex definition of POWER_MODE_CTRL register fields with BIT()
macro and use open-coded implementation for register manipulations.
