Dan Carpenter ae4aaae623 ALSA: bits vs bytes bug in snd_card_create() ...

commit 4c3773eda4 upstream.

The test here is intended intended to prevent shift wrapping bugs when
we do "1U << idx2".  We should consider the number of bits in a u32
instead of the number of bytes.

[fix another chunk similarly by tiwai]
