From addf2286331adc72a81de2179887671ecbf9f314 Mon Sep 17 00:00:00 2001 From: wangdicheng Date: Wed, 3 Jun 2026 17:10:59 +0800 Subject: [PATCH] ALSA: usb-audio: qcom: Improve error logging in USB offload Add error codes to error messages for better debugging. This helps identify the root cause when USB audio offload fails. Error messages now include the actual error code returned by xhci_sideband operations, making it easier to diagnose failures during USB audio offload setup.
