clocksource/drivers/samsung_pwm: Minor whitespace cleanup
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 Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Link: https://lore.kernel.org/r/20210506202729.157260-1-krzysztof.kozlowski@canonical.com
