Subject: [PATCH v2 2/4] asm-generic: avoid compiler warnings due to PCI_IOBASE
Date: Mon, 30 Jan 2023 08:27:05 +0100 [thread overview]
Message-ID: <20230130072707.2423294-3-ahmad@a3f.at> (raw)
In-Reply-To: <20230130072707.2423294-1-ahmad@a3f.at>
Some GCC versions take offence at PCI_IOBASE's default value of 0.
Hide warnings about this.
