[alsa-devel] [PATCH] sound: pci: ice1712: wm8776.c: Remove some unused functions
Removes some functions that are not used anywhere: snd_wm8776_set_master_mode() snd_wm8776_set_adc_if() snd_wm8776_set_dac_if()
This was partially found by using a static code analysis program called cppcheck.

I've a pair of these, and seeing patches to the driver reminded me to bring up the subject of word-clock sync.
I've managed to get the clock-sync working sometimes; either using an inter-card jumper, or light pipe between breakout boxes. However, they do seem to go out of sync without warning, or readily-discerned reason.
I'm far from technically clueless, but driver development is well-outside my comfort zone. Happy to work on this off-list if someone wants to let me know what probing/interrogation of the cards is needed. Could - probably - sniff traffic between a Windows VM and the cards, if given pointers; yes, even if that involves building a kernel.
