Hi Alexandre,
i think have traced down one problem we have to the latest patch in 3.12-rc:
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/drivers/gpio/gpiolib.c?id=be1a4b13089b1e18da83a549d49163ccad3c19ba
The problem is that by this patch a desc == NULL now returns -EINVAL while
earlier it did return an -EPROBE_DEFER, which I consider the better option.
By this -EINVAL, now some dependent drivers are no longer initialized.
So I't suggest to revert that.
Adding Linus since he authored the patch.
I suppose the behavior should not change indeed. But could you specify
which use-case now returns -EINVAL instead of -EPROBE_DEFER? It is not
obvious by just looking at the patch alone.
Thanks,
Alex.
