X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ca8b3fa7ea44738f02979dfdc72a1d75a27dcddb;p=linux-beck.git

staging: most: fix error return code in audio_probe_channel()

Fix to return a negative error code from the audio_set_hw_params() error
handling case instead of 0, as done elsewhere in this function.
