We could avoid this if we continue to ignore the return value like the current code. Or we may check ret at kfree() also? > + > +out: > + dma_release_channel(tmp_chan); > + > +dma_chan_err: > + fsl_asrc_release_pair(pair); > + > +req_pair_err: > + if (release_pair) > + kfree(pair); > + > + return ret; > } _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
