ASoC: sh: Drop superfluous PCM preallocation error checks
snd_pcm_lib_preallocate_pages() and co always succeed, so the error check is simply redundant. Drop it. Acked-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Reviewed-by: Jaroslav Kysela <perex@perex.cz> Acked-by: Mark Brown <broonie@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
