Subject: [PATCH V3 11/21] PCI: tegra194: Remove IRQF_ONESHOT flag during Endpoint interrupt registration
Date: Fri, 14 Oct 2022 00:08:44 +0530 [thread overview]
Message-ID: <20221013183854.21087-12-vidyas@nvidia.com> (raw)
In-Reply-To: <20221013183854.21087-1-vidyas@nvidia.com>
Tegra PCIe endpoint has a common interrupt that notifies hardware events
like link up, LTR send, etc. DMA completion event is also notified over
this interrupt. Remove IRQF_ONESHOT flag from interrupt registration and
allow DMA driver to share this interrupt.
