From c775ea4308949b5a8f47752a7a724df6b699c2fc Mon Sep 17 00:00:00 2001 From: Tzung-Bi Shih Date: Fri, 16 Jan 2026 08:10:18 +0000 Subject: [PATCH] gpio: cdev: Correct return code on memory allocation failure commit faff6846474e99295a139997f93ef6db222b5cee upstream. -ENOMEM is a more appropriate return code for memory allocation failures. Correct it.
