Subject: [PATCH 7/8] parisc/lba_pci: use container_of in LBA_DEV
Date: Mon, 14 Jan 2019 12:23:52 +0100	[thread overview]
Message-ID: <20190114112353.30616-8-hch@lst.de> (raw)
In-Reply-To: <20190114112353.30616-1-hch@lst.de>

Use the type safe container_of macros instead of a blind cast in
LBA_DEV, and turn the macro into an inline function.
