From e5565c24bb49f477c4326d2b5275ed88b50af1ef Mon Sep 17 00:00:00 2001 From: Henrik Grimler Date: Tue, 10 Sep 2024 20:37:18 +0200 Subject: [PATCH] pinctrl: exynos: fix type of count integer unsigned int count is used to capture return of dev_read_string_count. When an error occurs dev_read_string_count returns -ve, which can hence not be handled correctly. Use int instead of unsigned int so that errors are detected.
