Subject: [PATCH v2 5/9] iio: adis_buffer: don't push data to buffers on failure
Date: Thu, 22 Apr 2021 12:19:07 +0200 [thread overview]
Message-ID: <20210422101911.135630-6-nuno.sa@analog.com> (raw)
In-Reply-To: <20210422101911.135630-1-nuno.sa@analog.com>
There's no point in pushing data to IIO buffers in case 'spi_sync()'
fails.
