Subject: [PATCH 09/10] iio: imu: adis: assign read val in debugfs hook only if op successful
Date: Fri, 1 Nov 2019 11:35:04 +0200 [thread overview]
Message-ID: <20191101093505.9408-10-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20191101093505.9408-1-alexandru.ardelean@analog.com>
This was also caught by the `-Wmaybe-uninitialized` warning, which
(ironically as-is) it makes quite a lot of sense to do for this.
Fixes: 78026a6fde8f7 ("iio:imu:adis: Add debugfs register access support")
Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com>
