From d985b60f47893e8fd43989662111bebe78311cd1 Mon Sep 17 00:00:00 2001 From: Qianfeng Rong Date: Thu, 28 Aug 2025 15:53:57 +0800 Subject: [PATCH 1/3] ASoC: amd: use int type to store negative error codes Change the 'ret' variable from u32 to int to store negative error codes directly or returned by other functions. Storing the negative error codes in unsigned type, doesn't cause an issue at runtime but it's ugly as pants. Additionally, assigning negative error codes to unsigned type may trigger a GCC warning when the -Wsign-conversion flag is enabled. No effect on runtime.
