From dae01ec714fbbf3a71947668cb61cee4cc320647 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Thu, 31 Oct 2024 21:08:41 +0100 Subject: [PATCH] gpio: cdev: don't report GPIOs requested as interrupts as used GPIOs used as shared irqs can still be requested by user-space (or kernel drivers for that matter) yet we report them as used over the chardev ABI. Drop the test for FLAG_USED_AS_IRQ from gpio_desc_to_lineinfo().
