i2c: reduce parent checking to a NOOP in non-I2C_MUX case
Did you try reverting it? I am not sure this is the one.
Nope, not to mentio bisect. I have done bisect few times and I am
not going to waste whole day of compiling and booting new kernels.
Well, I intentionally asked for revert not bisect. Removing the #ifdef
can easily be done by hand if needed and will just need one recompile to
make sure.
Yes, but compiling whole Kernel is always pain. I dont certainly want to
do that just for testing some patches.
Crash disappeared whit that little patch.
Yes, still I'd like to understand where the BUG came from. There are
probably other driver in need of a fix, too.
Anyway, I am going to ask Mauro to merge that I2C parent patch and
maybe try to sent it stable too as it is likely a bit too late for
3.12 RC.
If it fixes a crash, I wouldn't consider it too late. Yet only given we
have understood this is a proper fix.
Was there a change in using CONFIG_I2C_COMPAT? Is it currently used?
Jean jsut pointed out on IRC that this patch likely fixes the issue:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=47b6e477ed4ecacddd1f82d04d686026e08dc3db
As that patch is already applied to 3.12 it should be fine. I was
running media master which is based 3.12-rc2.
So I am sending that patch to Kernel 3.13.

Antti
