Subject: iio: magnetometer: ak8975: replace usleep_range() with fsleep()
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=1fcd1fef65145caa465f2fe967ad7d90ddcfbc95;p=thirdparty%2Fkernel%2Fstable.git

iio: magnetometer: ak8975: replace usleep_range() with fsleep()

Replace usleep_range() calls with fsleep(), passing the minimum value
required by the sensor for hardware delays.

fsleep() automatically selects the optimal sleep mechanism, simplifying
driver code and time management.
