[PATCH 1/5] clocksource/drivers/samsung_pwm: Minor whitespace cleanup

From: Krzysztof Kozlowski
Date: Thu May 06 2021 - 16:29:50 EST


Cleanup the code to be slightly more readable and follow coding
convention - only whitespace. This fixes checkpatch warnings:

WARNING: Block comments should align the * on each line
WARNING: please, no space before tabs
WARNING: Missing a blank line after declarations
CHECK: Alignment should match open parenthesis
