[PATCH] ASoC: pcm: fix __le32 cast warning in snd_pcm_set_sync_per_card

[Ben Dooks]

In snd_pcm_set_sync_per_card() the le32 value is written to an u32
instead of an __le32 pointer. Fix the following warning by fixing
the type:

sound/soc/soc-pcm.c:2166:9: warning: incorrect type in argument 7 (different base types)
sound/soc/soc-pcm.c:2166:9:    expected int
sound/soc/soc-pcm.c:2166:9:    got restricted snd_pcm_format_t

Applied now (with the correction of the subject prefix -- it's ALSA
core, not ASoC-specific).
