Subject: [SPARC]: sbus/envctrl: replace schedule_timeout() with msleep_interruptible()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cb39d263e751f9cca8055bcacfe5ec863dfe2705;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[SPARC]: sbus/envctrl: replace schedule_timeout() with msleep_interruptible()

Use msleep_interruptible() instead of schedule_timeout() to guarantee
the task delays as expected. Change the units of poll_interval to
msecs as it is only used in this delay.
