Subject: kselftests: timers: Ease alarmtimer-suspend unreasonable latency value
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=acd5705d2d17a229b1aa0e549951ec66164b9379;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

kselftests: timers: Ease alarmtimer-suspend unreasonable latency value

On the hardware I have, resume latency from an alarm is often
2-3 seconds (with a fair amount of variability due to the RTC's
single second granularity). Having four seconds be the pass/fail
bar is maybe a little too tight, so extend this to 5 seconds.
