Subject: ALSA: ice1724: Remove superfluous loop over model table
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=3b0f7eeff697b04571a5c6329b7e8fdf8f8c85d9;p=uclinux-h8%2Flinux.git

ALSA: ice1724: Remove superfluous loop over model table

The ice1724 driver looks for the matching card_info entry twice, once
at reading EEPROM and another for the rest tasks in the probe call.
Reduce the second one by referring to the already assigned card_info
entry.
