Subject[PATCH v2] ALSA: hda/ca0132: Limit values for chip addresses to 32-bit
Date
With the previous unsigned long value clang generates warnings like
this:

sound/pci/hda/patch_ca0132.c:860:37: error: implicit conversion from
'unsigned long' to 'u32' (aka 'unsigned int') changes value from
18446744073709551615 to 4294967295 [-Werror,-Wconstant-conversion]
spec->curr_chip_addx = (res < 0) ? ~0UL : chip_addx;
~ ^~~~

Signed-off-by: Matthias Kaehlcke <mka@chromium.org>

Changes in v2:
- Remove unnecessary cast to u32
