iio: Fix iio_channel_has_info

Since the info_mask split, iio_channel_has_info() is not working correctly.
info_mask_separate and info_mask_shared_by_type, it is not possible to compare
them directly with the iio_chan_info_enum enum. Correct that bit using the BIT()
macro.

staging: rtl8192u: replace msleep(1) with usleep_range() in r819xU_phy.c

This patch fixes the following checkpatch warning:
WARNING: msleep < 20ms can sleep for up to 20ms

The implementation of msleep() is based on jiffies timeout
subsystem. Hence, its resolution is constrained by the value
of HZ tick rate. When HZ variable is configured to 100,
the jiffies variable is updated every 10 ms, so a timeout
of 1ms cannot be met using jiffies (it will be rounded up
to 10ms).

This patch replaces msleep(1) with usleep_range(1000, 1000).
usleep_range() uses hrtimers subsystem which is not bound
to HZ value and can provide microsecond-level resolution.

As suggested by Ian Abbott, comedi_set_spriv() can only be used to

Rename the function to comedi_alloc_spriv() and have it kzalloc() the
