ASoC: SOF: Propagate sof_get_ctrl_copy_params() error properly
This fixes a compile warning below by properly handling the error code from sof_get_ctrl_copy_params(): include/linux/kernel.h:843:43: warning: 'sparams.pl_size' may be used uninitialized in this function [-Wmaybe-uninitialized] sound/soc/sof/ipc.c:639:34: note: 'sparams.pl_size' was declared here The function returns an error before setting sparams.pl_size, so it'd assign an uninitialized value at a later point. Fixes: 53e0c72d98ba ("ASoC: SOF: Add support for IPC IO between DSP and Host") Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
