Subject: [PATCH 4/7] iio: adis16475: re-set max spi transfer
Date: Tue, 13 Apr 2021 13:21:02 +0200 [thread overview]
Message-ID: <20210413112105.69458-5-nuno.sa@analog.com> (raw)
In-Reply-To: <20210413112105.69458-1-nuno.sa@analog.com>
In case 'spi_sync()' fails, we would be left with a max spi transfer
which is not the one the user expects it to be. Hence, we need to re-set
it also in this error path.
Fixes: fff7352bf7a3c ("iio: imu: Add support for adis16475")
