Subject: ALSA: 6fire: Convert byte_rev_table uses to bitrev8
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=9547c0999e50fd624cab52f94a79f0fd27a7cb84;p=openwrt%2Fstaging%2Fblogic.git

ALSA: 6fire: Convert byte_rev_table uses to bitrev8

Use the inline function instead of directly indexing the array.

This allows some architectures with hardware instructions
for bit reversals to eliminate the array.
