ALSA: Force a cast to silence a warning from "sparse"
Some audio drivers are calling snd_dma_continuous_data(GFP_KERNEL) which makes "sparse" give a warning: $ make C=2 M=sound/usb modules ... sound/usb/6fire/pcm.c:625:25: warning: cast from restricted gfp_t sound/usb/caiaq/audio.c:845:41: warning: cast from restricted gfp_t sound/usb/usx2y/usbusx2yaudio.c:997:54: warning: cast from restricted gfp_t sound/usb/usx2y/usbusx2yaudio.c:1001:54: warning: cast from restricted gfp_t sound/usb/usx2y/usx2yhwdeppcm.c:774:54: warning: cast from restricted gfp_t sound/usb/usx2y/usx2yhwdeppcm.c:778:54: warning: cast from restricted gfp_t Add __force to the cast to silence the warning.
