the\ncontrol put operation fsl_xcvr_arc_mode_put() only returns 0 or a negative\nerror code, causing ALSA to not generate any change events.\n\nAdd a suitable check in the function before updating the arc_mode\nvariable.\n\nFixes: 28564486866f (\"ASoC: fsl_xcvr: Add XCVR ASoC CPU DAI driver\")\nSigned-off-by: Shengjiu Wang <shengjiu.wang@nxp.com>\n---\n sound/soc/fsl/fsl_xcvr.c | 11 +++++++++--\n 1
