Subject: [RFC 03/32] ACPI: Kconfig: add HAS_IOPORT dependencies
Date: Mon, 27 Dec 2021 17:42:48 +0100 [thread overview]
Message-ID: <20211227164317.4146918-4-schnelle@linux.ibm.com> (raw)
In-Reply-To: <20211227164317.4146918-1-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 depend on
HAS_IOPORT unconditionally.
