[PATCH 5.4 088/168] iio: st_sensors: rely on odr mask to know if odr can be set
From: Greg Kroah-Hartman
Date: Tue Apr 28 2020 - 14:41:33 EST
From: Lary Gibaud <yarl-baudig@xxxxxxxxxx>
commit e450e07c14abae563ad13b064cbce9fdccc6bc8d upstream.
Indeed, relying on addr being not 0 cannot work because some device have
their register to set odr at address 0. As a matter of fact, if the odr
can be set, then there is a mask.
Sensors with ODR register at address 0 are: lsm303dlh, lsm303dlhc, lsm303dlm
Fixes: 7d245172675a ("iio: common: st_sensors: check odr address value in st_sensors_set_odr()")
