Subject: [RFC v2 10/39] gpio: add HAS_IOPORT dependencies
Date: Fri, 29 Apr 2022 15:50:16 +0200	[thread overview]
Message-ID: <20220429135108.2781579-19-schnelle@linux.ibm.com> (raw)
In-Reply-To: <20220429135108.2781579-1-schnelle@linux.ibm.com>

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them.
