Subject: [PATCH 3.18 02/47] x86: i8259: export legacy_pic symbol
Date: Fri, 23 Mar 2018 10:54:53 +0100	[thread overview]
Message-ID: <20180323094248.227501251@linuxfoundation.org> (raw)
In-Reply-To: <20180323094248.117679641@linuxfoundation.org>

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hans de Goede <hdegoede@redhat.com>


[ Upstream commit 7ee06cb2f840a96be46233181ed4557901a74385 ]

The classic PC rtc-coms driver has a workaround for broken ACPI device
nodes for it which lack an irq resource. This workaround used to
unconditionally hardcode the irq to 8 in these cases.

This was causing irq conflict problems on systems without a legacy-pic
so a recent patch added an if (nr_legacy_irqs()) guard to the
workaround to avoid this irq conflict.

nr_legacy_irqs() uses the legacy_pic symbol under the hood causing
an undefined symbol error if the rtc-cmos code is build as a module.

This commit exports the legacy_pic symbol to fix this.
