So I assumed that Beagle bone has only one USB port in host mode because
the micro USB connector had an USB-UART there. I was wrong a little. The
second port runs on host mode, but the micro USB plug is connected to an
internal HUB with two ports: one to the USB-UART and one to musb
instance one.
For that reason, this patch enables both ports: the primary in device
mode only and the second in host mode only.

This is what I observe:
On the first connect, the musb starts with DEVCTL.Session set. On
disconnect, musb_core calls try_idle. That functions removes the Session
bit signalizing that the session is over (something that only in OTG is
required). A new device, that is plugged, is no longer recognized.
I've setup a timer and checked the DEVCTL register and I haven't seen a
change in VBus and I saw the B-Device bit set. After setting the IDDIG
into A mode and forcing the device to behave like a A device, I didn't
see a change.
Neither VBUS goes to 0b11 nor does a session start request comes.
In the TI-v3.2 kernel they skip to call musb_platform_try_idle() in the
OTG_STATE_A_WAIT_BCON state while not in OTG mode.
Since the second port hast a standard A plug the patch changes the port
to run in host mode only and skips the timer which would remove
DEVCTL.Session so we can reconnect to another device later.

Quite early on init there is an vbus / drvvbus interrupt comming and the
dsps code sets is_active to one. As a result we see a lot of
|musb_bus_suspend 2459: trying to suspend as a_wait_bcon while active
until a device is plugged in with pm_runtime enabled in the kernel.
After checking davinci, am35, da8xx I noticed that dsps is actually the
only one doing this.
So remove it and we won't flooded with mesages and the idle port can be

musb_shutdown() removes always USB host and device.
musb_init_controller() adds host and device depending on port_mode. If
port mode is set to HOST then the removal of UDC leads only to:
|(NULL device *): gadget not registered.
and nothing else happens. If port mode is set to DEVICE and we remove
the host then we oops in usb_remove_hcd().
This patch ensures that we only remove host in OTG/host mode and device
only in OTG/device mode to avoid any trouble.

If usb_add_function() fails then the currently processed function
is already not in the list in struct config_usb_cfg, and neither is it
in the list in struct usb_configuration. At the err_purge_funcs label the
purge_config_funcs() is called, which iterates over all configurations,
and in each configuration it iterates over all _successfully_ added
functions, and moves them back from the list in struct usb_configuration
to the list in struct config_usb_cfg. BUT the function which has just
failed adding and caused the unwind process is not taken care of and
is effectively lost.
This patch modifies the configfs_composite_bind() function so that if
the usb_add_function() fails, then the currently processed function
is returned to the list in struct config_usb_cfg.
It would be tempting to delay the list_del() in question after
usb_add_function() invocation, but a struct list_head (&f->list) cannot be
stored in more than one list at the same time, so the list_del() must
be called before usb_add_function(). Hence, the solution is to list_add()
after usb_add_function() in case of error.

Hi Greg,
This is the first of two steps to fix your usb-linus and usb-next trees.
As I mentioned, commit 4fae6f0fa8 "USB:
handle LPM errors during device suspend correctly" was incorrectly added
to usb-next when it should have been added to usb-linus and marked for
stable.
Two port power off bug fixes touch the same code that patch touches, but
it's not easy to simply move commit 4fae6f0f patch to usb-linus because
commit 28e861658e "USB: refactor code for
enabling/disabling remote wakeup" also touched those code sections.
I propose a two step process to fix this:
1. Pull these four patches into usb-linus.
2. Revert commit 28e861658e from usb-next.
Merge usb-linus into usb-next, and resolve the conflicts.
I will be sending pull requests for these steps.
This pull request is step two.

usb-serial-simple uses an unknown stringify macro that make

This can be a problem when two drivers have the same (wrong) name:
kernel: usbcore: registered new interface driver usb_serial_simple
kernel: usbserial: USB Serial support registered for stringify(vendor)
kernel Error: Driver 'stringify(vendor)' is already registered, aborting...
kernel: usbserial: problem -16 when registering driver stringify(vendor)

Before the fix:
$ strings drivers/usb/serial/usb-serial-simple.o

After the fix:
$ strings drivers/usb/serial/usb-serial-simple.o

However that function gets called from truncate path and thus inode

the file needn't be ever open since mount. Calling
jbd2_journal_file_inode() without jinode attached results in the oops.
We fix the problem by attaching jinode to inode also in ext4_truncate()

ARM: Fix the world famous typo with is_gate_vma()
Pull m68k fixes from Geert Uytterhoeven:
"These are two critical fixes, needed by distro kernels, and thus also
destined for stable:
- The do_div() commit fixes a crash in mounting btrfs volumes, which
was a regression from 3.2,
- The ARAnyM fix allows to have NatFeat drivers as loadable modules,
which is needed for initrds"
* 'for-3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/geert/linux-m68k:
m68k: Truncate base in do_div()
m68k/atari: ARAnyM - Fix NatFeat module support
another Exynos clock patch which fixes a regression that prevents the
video pipeline from functioning on that platform.

PM / QoS: Fix workqueue deadlock when using pm_qos_update_request_timeout()
This batch contains a few USB audio fixes, a couple of HD-audio quirks,
various small ASoC driver fixes in addition to an ASoC core fix that
may lead to memory corruption.
Unfortunately slightly more volume than the previous pull request, but
all are reasonable regression fixes.
