Wolfram,
Phil email address was not valid anymore, so could you Wolfram, as a I2C
subsystem maintainer, look and comment that. The fact is that my driver
has a 3.12 regression and I want to know where it is coming from to make
decision what to do!
regards
Antti

Hello Phil and Wolfram,
I found one of my drivers was crashing when DTV USB stick was plugged.
Patch in that mail patch fixes the problem.
I quickly looked possible I2C patches causing the problem and saw that
one as most suspicions:
commit 3923172b3d700486c1ca24df9c4c5405a83e2309
i2c: reduce parent checking to a NOOP in non-I2C_MUX case
My config has no CONFIG_I2C_MUX set currently, but I am not sure how it
has been earlier.
Any idea?
regards
