Series pinctrl: Convert struct group_desc to use struct pingroup | expand

Commit Message

struct group_desc is a particular version of the struct pingroup
with associated opaque data. Start switching pin control core and
drivers to use it explicitly.

Hmm... I have compiled tested on Linux Next it several times, I can't reproduce
this neither with GCC nor with LLVM.
