Subject: [PATCH 1/4] uio: uio_cif: use devm_kzalloc() for uio_info object
Date: Thu, 19 Nov 2020 17:49:00 +0200 [thread overview]
Message-ID: <20201119154903.82099-1-alexandru.ardelean@analog.com> (raw)
The uio_info object is free'd last, so it's life-time is tied PCI device
object. Using devm_kzalloc() cleans up the error path a bit and the exit
path.
