ALSA: via82xx: Fix endianness annotations
The internal page tables are in little endian, hence they should be __le32 type. This fixes the relevant sparse warnings: sound/pci/via82xx.c:454:60: warning: incorrect type in assignment (different base types) sound/pci/via82xx.c:454:60: expected unsigned int [usertype] sound/pci/via82xx.c:454:60: got restricted __le32 [usertype] .... No functional changes, just sparse warning fixes. Link: https://lore.kernel.org/r/20200206163152.6073-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
