From fcbc3aaccfd57c7e71eac36bf1a8f063f19ceefa Mon Sep 17 00:00:00 2001 From: Yang Li Date: Tue, 16 May 2023 16:11:16 +0800 Subject: [PATCH] ASoC: SOF: ipc4-topology: Fix an unsigned comparison which can never be negative The return value from the call to sof_ipc4_get_valid_bits() is int. However, the return value is being assigned to an unsigned int variable 'out_ref_valid_bits', so making it an int.
