From 2fef71da84f51c395c367f9e9a9ebb74a3f0a5a8 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 18 Jul 2022 15:04:05 +0100 Subject: [PATCH] ASoC: nau8821: Don't unconditionally free interrupt [ Upstream commit 2d86cef353b8f3d20b16f8c5615742fd6938c801 ] The remove() operation unconditionally frees the interrupt for the device but we may not actually have an interrupt so there might be nothing to free. Since the interrupt is requested after all other resources we don't need the explicit free anyway, unwinding is guaranteed to be safe, so just delete the remove() function and let devm take care of things.
