[patch 10/21] media/cpia: replace schedule_timeout() with msleep_interruptible()

[patch 10/21] media/cpia: replace schedule_timeout() with msleep_interruptible()

[janitor]

Any comments would be appreciated.

Description: Use msleep_interruptible() instead of schedule_timeout() to
guarantee the task delays as expected.
