From: wangdicheng Date: Wed, 3 Jun 2026 09:10:59 +0000 (+0800) Subject: ALSA: usb-audio: qcom: Improve error logging in USB offload X-Git-Url: http://git.ipfire.org/gitweb/?a=commitdiff_plain;h=addf2286331adc72a81de2179887671ecbf9f314;p=thirdparty%2Flinux.git 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.
