ALSA: sb: Fix sparse warning wrt PCM format type
The PCM format type is with __bitwise, and it can't be converted from integer implicitly. Instead of an ugly cast, declare the function argument of snd_sb_csp_autoload() with the proper snd_pcm_format_t type. This fixes the sparse warnings like: sound/isa/sb/sb16_csp.c:743:22: warning: restricted snd_pcm_format_t degrades to integer Signed-off-by: Takashi Iwai <tiwai@suse.de>
