Subject: [PATCH v2 6/9] iio: adis_buffer: update device page after changing it
Date: Thu, 22 Apr 2021 12:19:08 +0200	[thread overview]
Message-ID: <20210422101911.135630-7-nuno.sa@analog.com> (raw)
In-Reply-To: <20210422101911.135630-1-nuno.sa@analog.com>

With commit 58ca347b9b24 ("iio: adis_buffer: don't push data to buffers on
failure"), we return if 'spi_sync()' fails which would leave
'adis->current_page' in an incoherent state. Hence, set this variable
right after we change the device page.
