Subject: [ 07/53] ALSA: ali5451: remove irq enabling in pointer callback

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Denis Efremov <yefremov.denis@...il.com>

commit dacae5a19b4cbe1b5e3a86de23ea74cbe9ec9652 upstream.

snd_ali_pointer function is called with local
interrupts disabled. However it seems very strange to
reenable them in such way.

Found by Linux Driver Verification project (linuxtesting.org).
