X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8d06cd25f745db8905e303cc915932cc50aa0ae5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

iio: magn: ak8975: make sure to power down at remove()

The code was not powering the magnetometer down properly at
remove(): just cutting the regulators without first setting the
device in power off mode. Fix this.
