udc-core now handles that for us, which means
we can remove it from our driver.

We don't need the ->register_my_device flag
anymore because all UDC drivers have been
properly converted.
Let's remove every history of it.

By simply setting a flag, we can drop some
boilerplate code.

This patch converts the drivers in drivers/usb/* to use the
module_platform_driver_probe() macro which makes the code smaller and
a bit simpler.

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."

The STOTG04 is an replacement for ISP1301.
Most of the registers on STOTG04 are the same as on ISP1301, but the
register ISP1301_I2C_OTG_CONTROL_2 (address 0x10) doesn't exist on the
ST part.
This is a work around for this by using the interrupt source register that
should behave the same on both parts and has the needed information.

Change the call to PTR_ERR to access the value just tested by IS_ERR.
The semantic match that finds this problem is as follows:

The lpc32xx_udc driver supported only one controller by defining a global
static struct for it. This patch enables multiple instances of the controller
by dynamic allocation of the struct at probe(). A static struct is kept as a
template on initialization since it does some complex preset, reflecting fixed
hardware endpoint structure.

This patch removes the utilization of struct usb_endpoint_descriptor, as done
by other drivers also. This was done on request by the USB gadget maintainers,
since this API is obsoleted.

usb: gadget: patches for v3.6 merge window
This is quite a big pull request and contains patches
all over the place.
omap_udc is now a bit cleaner after removing omap2 support,
fixing some checkpatch.pl warnings and errors, switching over
to generic map/unmap routines and preventing a NULL pointer
de-reference.
s3c-hsotg has been switched over to devm_* API, got some
locking fixes and improvements and it also got an implementation
for the pullup() method.
the mass storage gadgets changed default value of the removable
parameter, dropped some unused options and made "file" and "ro"
module_parameters read-only in some cases.
ffs function got support for HID descriptor.
Some UDCs have been converted to clk_prepare_enable() and
clk_disable_unprepare().
Marvell now got support for its USB3 controller in mainline
after introducing its mv_u3d_core.c driver.
