From aee32b594f2c2332e73001938a174fb1403193f2 Mon Sep 17 00:00:00 2001 From: Danny Kaehn Date: Fri, 10 Feb 2023 11:00:44 -0600 Subject: [PATCH] HID: cp2112: Fix driver not registering GPIO IRQ chip as threaded [ Upstream commit 37f5b858a66543b2b67c0288280af623985abc29 ] The CP2112 generates interrupts from a polling routine on a thread, and can only support threaded interrupts. This patch configures the gpiochip irq chip with this flag, disallowing consumers to request a hard IRQ from this driver, which resulted in a segfault previously.
