Subject: [PATCH V5 2/3] PCI: pciehp: reuse pciehp_mask/unmask_irq() in reset_slot()
Date: Mon, 2 Jul 2018 18:52:46 -0400 [thread overview]
Message-ID: <1530571967-19099-3-git-send-email-okaya@codeaurora.org> (raw)
In-Reply-To: <1530571967-19099-1-git-send-email-okaya@codeaurora.org>
Now that we have individual functions to mask/unmask hotplug interrupts
avoid code duplication and reuse the new API in multiple places.
