Subject: [PATCH 03/37] ACPI: add dependency on HAS_IOPORT
Date: Fri, 29 Apr 2022 15:50:02 +0200	[thread overview]
Message-ID: <20220429135108.2781579-5-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. As ACPI always uses I/O port access we simply depend
on HAS_IOPORT.
