[PATCH 5.4 088/168] iio: st_sensors: rely on odr mask to know if odr can be set

[Greg Kroah-Hartman]

From: Lary Gibaud <yarl-bau...@mailoo.org>

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

st_sensors_set_odr()")
