Subject: [PATCH v4 2/5] resource: Add irqresource_disabled()
Date: Tue, 1 Dec 2020 01:35:56 +0800 [thread overview]
Message-ID: <1606757759-6076-3-git-send-email-john.garry@huawei.com> (raw)
In-Reply-To: <1606757759-6076-1-git-send-email-john.garry@huawei.com>
Add a common function to set the fields for a irq resource to disabled,
which mimics what is done in acpi_dev_irqresource_disabled(), with a view
to replace that function.
Signed-off-by: John Garry <john.garry@huawei.com>
