commit 11432050f070810ba139d0226344eef120c3a559 upstream.
This patch fixes an issue that the NULL pointer dereference happens
when we uses g_audio driver. Since the g_audio driver will call
usb_ep_disable() in afunc_set_alt() before it calls usb_ep_enable(),
the uep->pipe of renesas usbhs driver will be NULL. So, this patch
adds a condition to avoid the oops.

Use the recently introduced usb_gadget_giveback_request() in favor of
direct invocation of the completion routine.
All places in drivers/usb/ matching "[-.]complete(" were replaced with a
call to usb_gadget_giveback_request(). This was compile-tested with all
ARM drivers enabled and runtime-tested for musb.

This patch fixes the condition of is_done in usbhsf_dma_push_done().
This function will be called after a transmission finished by DMAC.
So, the function should check if the transmission packet is short packet
or not. Also the function should call try_run to send the zero packet
by the pio handler if the "*is_done" is not set. Otherwize, the
transaction will not finish if a gadget driver sets the "zero" flag
in a transmission.

This patch protects the mod->irq_bempsts and mod->irq_brdysts by
spin lock in the usbhs_status_get_each_irq() because other functions
will write them during spin lock. Otherwise, the driver will clears
the BRDYSTS and/or BEMPSTS wrongly, and then, the transaction will not
finish.
Also since the driver should use the INTSTS0 and BRDYSTS and BEMPSTS
as the same timing, the patch protects them.

Some gadget drivers will call usb_ep_queue() more than once before
the first queue doesn't finish. However, this driver didn't handle

usbhs_pkt_handle using the "running" flag. Otherwise, the oops below
happens if we use g_ncm driver and when the "iperf -u -c host -b 200M"

This patch fixes an issue that the renesas_usbhs driver in gadget mode
cannot work correctly even if I disabled DMAC of the driver when I used
the g_zero driver and the testusb tool.
When a usb cable is re-connected, the renesas_usbhs driver calls the
usbhsp_flags_init() (via usbhs_hotplug() --> usbhs_mod_call(start) -->
usbhsg_try_start() --> usbhs_pipe_init()). However, the driver doesn't
call the usbhsp_flags_init() when usbhsg_ep_disable() is called.
So, if a gadget driver calls usb_ep_enable() and usb_ep_disable() again
and again, the renesas_usbhs driver will output the following log:
renesas_usbhs renesas_usbhs: can't get pipe (BULK)
renesas_usbhs renesas_usbhs: wrong recip request

configfs-based binding.
Misc Fixes and Clean Ups:

This patch adds "maxpacket_limit" to struct usb_ep. This field contains
maximum value of maxpacket supported by driver, and is set in driver probe.
This value should be used by autoconfig() function, because value of field
"maxpacket" is set to value from endpoint descriptor when endpoint becomes
enabled. So when autoconfig() function will be called again for this endpoint,
"maxpacket" value will contain wMaxPacketSize from descriptior instead of
maximum packet size for this endpoint.
For this reason this patch adds new field "maxpacket_limit" which contains
value of maximum packet size (which defines maximum endpoint capabilities).
This value is used in ep_matches() function used by autoconfig().
Value of "maxpacket_limit" should be set in UDC driver probe function, using
usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function
set choosen value to both "maxpacket_limit" and "maxpacket" fields.
This patch modifies UDC drivers by adding support for maxpacket_limit.

DMAEngine uses IRQ if dma_request_channel() was called,
and it is using devm_request_irq() today,
OTOH, dma_request_channel() will be called when each
USB connection happened on this driver.
This means same IRQ will be requested many times
whenever each USB connected,
and this IRQ isn't freed when USB disconnected.

There were surprisingly quite a few users left, but all of them

f_mass_storage removed some dead code, which is always great ;-)
There's also a big cleanup to the gadget framework from Sebastian
which gets us a lot closer to having only function drivers in
kernel and move over to configfs-based binding.
Other than these, there's the usual set of cleanups: s3c UDCs are

USB gadget patches from Felipe:
"usb: gadget: patches for v3.8
renesas_usbhs implements ->pullup() method, switches over
to devm_request_irq(), adds support for DMA Engine and
got a few miscelaneous cleanups.
The NCM gadget got an endianness fix and the Ethernet
gadget a frame size fix.
We're finally removing the g_file_storage gadget and
sticking to g_mass_storage and the new tcm_usb_gadget
gadgets since that was a huge duplicaton of effort anyway.
While removing g_file_storage, we also had to fix a bunch
of defconfigs which were still pointing to the old gadget.
There's a big series getting us closer to being able to
introduce our configfs interface. The series converts
functions into loadable modules which will, eventually,
be registered to the configfs interface.
Other than that there's the usual typo fixes and miscelaneous
cleanups all over the place."

because pipe kept BUF PID even though it doesn't have enough buffer.
To avoid this issue, renesas_usbhs can use transfer counter.

renesas_usbhs attaches pipe to endpoint when urb was queued, and it will be
detached when transfer was done. Multi device controlling was enabled by this
behavior.
Now renesas_usbhs driver tried to wait until detaching if urb was queued to
endpoint which already has been attached to pipe, and it created strange driver
behavior.
But it can re-use this attached pipe if multi urb was queued. This patch
