Subject: [Patch V2 03/13] platform-msi: Provide default irq_chip:: Ack
Date: Fri, 26 Feb 2021 12:11:07 -0800 [thread overview]
Message-ID: <1614370277-23235-4-git-send-email-megha.dey@intel.com> (raw)
In-Reply-To: <1614370277-23235-1-git-send-email-megha.dey@intel.com>
From: Thomas Gleixner <tglx@linutronix.de>
For the upcoming device MSI support it's required to have a default
irq_chip::ack implementation (irq_chip_ack_parent) so the drivers do not
need to care.
