Subject: iio: accel: kxsd9: fix the usage of spi_w8r8()
From: Linus Walleij <linus.walleij@linaro.org>
commit 0c1f91b98552da49d9d8eed32b3132a58d2f4598 upstream.
These two spi_w8r8() calls return a value with is used by the code
following the error check. The dubious use was caused by a cleanup
patch.
Fixes: d34dbee8ac8e ("staging:iio:accel:kxsd9 cleanup and conversion to iio_chan_spec.")
