Since upgrading from 3.12.24 kernel to 3.14.10, and today, .12 kernel log

I tried setting verbose usb debug to see if it offers any more explanations,
but it shows nothing more.
The device is Huawei E160, but is identified as (and always has been) an

Did somthing break between 3.12 and 3.14? Rather annoying at how fast and
large kernel.log is geting.
Any chance you can use 'git bisect' to try to find the problem commit in
the kernel tree?

There has only been one change to the option driver (apart from added device
id's) and that is
Johan Hovolds
[PATCH 21/63] USB: option: fix runtime PM handling
commit 5ff2117cf81c53f2b1e3e47a38451c792da4b330
His two other patches:
[PATCH 22/63] USB: option: fix line-control pipe direction
[PATCH 23/63] USB: option: add missing usb_mark_last_busy
seems to have taken a detour, they are still not in stable or LTS
Johan?
Johan's on vacation, what are the git commit ids of these patches in
Linus's tree?
thanks,
greg k-h
Aah, all 3 patches are taken in 3.16-rc1
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/diff/drivers/usb/serial/option.c?id=e5c4ecdc55b6d824365ba7964bcd3185223f9688
and the runtime PM patch 21/63 also went to stable, so only one one
culprit then.
