[alsa-devel] [PATCH 07/14] ALSA: intel8x0: Proper endian notations

The BD address tables in intel8x0 driver are in little-endian, hence
they should be represented as __le32 instead u32.
Spotted by sparse, warnings like:
sound/pci/intel8x0.c:688:40: warning: incorrect type in assignment (different base types)
