From 4451e8e8415e4ef48cdc763d66855f8c25fda94c Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Tue, 23 Jan 2024 12:08:18 -0600 Subject: [PATCH] pinctrl: amd: Add IRQF_ONESHOT to the interrupt request On some systems the interrupt is shared between GPIO controller and ACPI SCI. When the interrupt is shared with the ACPI SCI the flags need to be identical. This should fix the GPIO controller failing to work after commit 7a36b901a6eb ("ACPI: OSL: Use a threaded interrupt handler for SCI"). ``` [ 0.417335] genirq: Flags mismatch irq 9. 00000088 (pinctrl_amd) vs. 00002080 (acpi) [ 0.420073] amd_gpio: probe of AMDI0030:00 failed with error -16 ``` Cc: Rafael J.
