The checkpatch.pl script flagged a warning regarding the use of
msleep() for less than 20ms. msleep() relies on jiffies and can
be inaccurate for short durations, leading to inefficient delays.

Replace msleep(10) with usleep_range(10000, 12000) to allow for
timer coalescing. This gives the kernel scheduler a 2ms window
to group wakeups, improving overall system power efficiency
while maintaining the required 10ms minimum delay.

The new API is fsleep().

Greg has already NAKed this change.
