From 862523297778775a0543110dcbf2ca832782f675 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 28 Nov 2018 17:57:56 +0100 Subject: gpiolib-acpi: Remove unnecessary WARN_ON from acpi_gpiochip_free_interrupts acpi_gpiochip_alloc_event only continues allocating an event and adding it to the list if gpiochip_request_own_desc does not return an error. So events with an error desc are never placed on the events list and this check is really not necessary.
