iio: imu: st_lsm6dsx: simplify data ready pin parsing
Simplify st_lsm6dsx_of_get_drdy_pin routine since of_property_read_u32 error conditions are already managed in st_lsm6dsx_get_drdy_reg() Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@st.com> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
