ac97#0-N entries are identical there for both codecs, this is because
ac97_codec_read/write always accesses primary codec. Try next patch
please.

May be au8810 use different set of MMIO to read/write and report
status of the audio codec and modem codec ?
au8810.h
#define VORTEX_MODEM_CTRL 0x291ac
Make sure you have a BACKUP of all your data before you peform testing
on the modem.
It's not easy to hack the modem since we don't have any datasheet of
au8810 and MOT6269353. (AC-link between them)
