[PATCH] gpio: cdev: don't report GPIOs requested as interrupts as used
From: Bartosz Golaszewski
Date: Thu Oct 31 2024 - 16:08:58 EST
From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>
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().
