ASoC: amd: acp-mach-common: Add missing error check for clock acquisition

Assigner: Linux
Reserved: 01.05.2026 Published: 08.05.2026 Updated: 08.05.2026

In the Linux kernel, the following vulnerability has been resolved:

ASoC: amd: acp-mach-common: Add missing error check for clock acquisition

The acp_card_rt5682_init() and acp_card_rt5682s_init() functions did not check the return values of clk_get(). This could lead to a kernel crash when the invalid pointers are later dereferenced by clock core functions.

Fix this by: 1. Changing clk_get() to the device-managed devm_clk_get(). 2. Adding IS_ERR() checks immediately after each clock acquisition.
