From 03f84b3baba7836bdfc162c19288d5ce1aa92890 Mon Sep 17 00:00:00 2001 From: Siddharth Vadapalli Date: Tue, 27 Aug 2024 17:54:21 +0530 Subject: [PATCH] PCI: dra7xx: Fix threaded IRQ request for "dra7xx-pcie-main" IRQ MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Commit da87d35a6e51 ("PCI: dra7xx: Use threaded IRQ handler for "dra7xx-pcie-main" IRQ") switched from devm_request_irq() to devm_request_threaded_irq() for the "dra7xx-pcie-main" interrupt. Since the primary handler was set to NULL, the "IRQF_ONESHOT" flag should have also been set. Fix this.
