iio: common: st_sensors: fix channel data parsing
Using realbits as i2c/spi read len, when that value is not byte aligned (e.g 12 bits), lead to skip msb part of out data registers. Fix this taking into account scan_type.shift in addition to scan_type.realbits as read length: read_len = DIV_ROUND_UP(realbits + shift, 8) This fix has been tested on 8, 12, 16, 24 bit sensors Fixes: e7385de5291e ("iio:st_sensors: align on storagebits boundaries") Signed-off-by: Lorenzo Bianconi <lorenzo.bianconi@st.com> Tested-by: Linus Walleij <linus.walleij@linaro.org> Cc: <Stable@vger.kernel.org> Signed-off-by: Jonathan Cameron <jic23@kernel.org>
