As per Documentation/timers/timers-howto.txt Msleep < 20ms can sleep for
up to 20ms. so use usleep_range.

Thanks and applied to the togreg branch of iio.git and pushed out as testing
for the autobuilders to play with it.

Whilst we are here, there is a 'false' warning that we should clear up at
somepoint (from sparse)

CHECK   drivers/iio/gyro/mpu3050-core.c
drivers/iio/gyro/mpu3050-core.c:544:48: warning: incorrect type in assignment (different base types)
drivers/iio/gyro/mpu3050-core.c:544:48:    expected restricted __be16 <noident>
drivers/iio/gyro/mpu3050-core.c:544:48:    got int

Line in question is setting the __be16 value to 0xAAAA where endian choice has
no effect.  I'll send out the trivial 'fix' in a minute.  Give the compiler
can sort it out at build time it should make no actual difference.

Usual arguments apply for why we bother to suppress 'false' build warnings
like this...

Anyhow patch shortly.

Jonathan
