ALSA: pcm/oss: mark snd_pcm_plug_slave_format arg as const
Only one of the two declarations has the const modifier in the
argument list, so we get a warning when CONFIG_SND_PCM_OSS_PLUGINS
is disabled:
sound/core/oss/pcm_oss.c: In function 'snd_pcm_oss_change_params':
sound/core/oss/pcm_oss.c:898:47: error: passing argument 2 of 'snd_pcm_plug_slave_format' discards 'const' qualifier from pointer target type [-Werror=discarded-qualifiers]
This makes the two declarations match again.
Fixes: e76bf3c4b4e4 ("ALSA: pcm/oss: refer to parameters instead of copying to reduce usage of kernel stack")
