The get_mask callback is still undefined for ice1724...

That is weird. I split the original commit using interactive git rebase + edit + add interactive into three new commits - get-mask, pro-rate-locked and all the external-clock. I commited all of them, rechecked git status before continuing with rebase - nothing uncommitted was left, no outstanding changes. But the get_mask commit did not show up in the subsequent interactive rebase list of commits. I was looking for it, I thought I found it in the main gpio-methods commit but overlooked that it is for ice1712.c only.

The method and its callback has disappeared from my master after the rebase. Do you have any idea what could have gone wrong?

I will fix and repost in the evening.

We don't need this header here. (Ditto for ak4114.h and pt2258.h. They were needed because the structure were referred in ice1712.h. But they are now gone to the local structure, so no need in the common header.)

Yesterday I moved it from ice1712.h to quartet.h. The build succeeded but when loading the new snd-ice1724 module I got dmesg messages about unknown references to ak4113 methods used in the quartet code. That is why I left the include in ice1712.h which works fine.

Unfortunately my knowledge of the build/load infrastructure is very limited, I can do just copy/paste in this area :)

Thanks,

Pavel.
