Since commit a72952672005 ("ASoC: sgtl5000: add avc support") the
following kernel crash happens after running a 'reboot' command:
ALSA: Storing mixer settings...
[ 20.031604] Unable to handle kernel paging request at virtual address fffffffe
[ 20.039268] pgd = de2a0000
[ 20.041999] [fffffffe] *pgd=8fffd861, *pte=00000000, *ppte=00000000
[ 20.048387] Internal error: Oops: 80000007 [#1] SMP ARM
The function that takes a kcontrol parameter and returns the
codec that registered the control is snd_soc_kcontrol_codec(),
so use the correct function to fix the problem.
Fixes: a72952672005 ("ASoC: sgtl5000: add avc support")
