3.18.34 and 4.7-rc1 are affected too.
The bug seems to have been introduced by "add I/O watchdog for orphan
TDs" (81e38333). I couldn't run bisect because those old kernels don
Hello all,
I'm bringing the linux kernel for the STM32F4 MCU (mmu-less). This MCU
has two DWC2 cores on it:one for USB OTG HS and one for USB OTG FS.
I was able to make the DWC2 driver to work in FS mode using a internal
phy in both cores (HS and FS), but I had to patch it (in a bad way,

Stop using the return value of platform_device_register_full() to get to
the struct musb in sunxi_musb_work(). If a gadget has been registered
(insmod-ed) before the musb driver, then musb_start will get called
from the musb_core probe function and sunxi_musb_work() may run before
platform_device_r
The comment is wrong, glue is devm_kzalloc-ed mem attached to the
"allwinner,sun4i-a10-musb" compatible platform-dev. Where as
glue->musb_pdev is a newly created "musb-hdrc" platform-dev.

Hi,
Why high-bandwidth USB 1.1 isochronous devices don't work on 2.0 hosts?
I have an ADSL modem of this kind which I would like to use on a
companion-less 2.0 host in my router, but I can't because it fails with
ENOSPC errors. Same thing happens on my PC when connected through a 2.0
hub, but it
