The current ST Micro Connect Lite uses the FT4232H hi-speed quad USB
UART FTDI chip. It is also possible to drive STM reference targets
populated with an on-board JTAG debugger based on the FT2232H chip with
the same STMicroelectronics tools.

For this reason, the ST Micro Connect Lite PIDs should be
ST_STMCLT_2232_PID: 0x3746
ST_STMCLT_4232_PID: 0x3747

usb: urgent fixes for v3.10 merge window

Here are some late urgent fixes for v3.10 merge window.

All of these errors were introduced by recent commits
which are in linux-next.

f_obex, multi and cdc2 gadget drivers have learned to
return a proper error code when something goes wrong.

usb_bind_phy() was mistakenly placed into .init.text
section which caused Section mismatch warnings and undefined
reference compile errors.

f_source_sink had a copy-paste error which is now corrected.

g_zero got a memory leak plugged.

Two defconfigs got fixed to enable the newly introduced
CONFIG_USB_PHY.

Commit edc7cb2e (usb: phy: make it a menuconfig) makes USB_MXS_PHY
be a sub-item of menuconfig symbol USB_PHY.  This change gets the
selection of CONFIG_USB_MXS_PHY in mxs_defconfig lost.  Hence the
boot stops at the point below.

  [    1.600867] ci_hdrc ci_hdrc.0: doesn't support gadget
  [    1.606282] ci_hdrc ci_hdrc.0: EHCI Host Controller
  [    1.613522] ci_hdrc ci_hdrc.0: new USB bus registered, assigned bus number 1

Add CONFIG_USB_PHY to have the CONFIG_USB_MXS_PHY selection back to
work.

It looks like section mismatch. Fix by removing the

Now that Joe cleaned up the init/exit functions, we can just get rid of

now use.

Use a more current logging style with dev_printk
where possible.

o Convert uses of US_DEBUGP to usb_stor_dbg
o Add "struct us_data *" to usb_stor_dbg uses
o usb_stor_dbg now uses struct device */dev_vprint_emit
o Removed embedded function names
o Coalesce formats
o Remove trailing whitespace
o Remove useless OOM messages
o Remove useless function entry/exit logging
o Convert some US_DEBUGP uses to dev_info and dev_dbg

Object size is slightly reduced when debugging
is enabled, slightly increased with no debugging
because some initialization and removal messages
are now always emitted.

When usbfs receives a ctrl-request from userspace it calls check_ctrlrecip,
which for a request with USB_RECIP_ENDPOINT tries to map this to an interface
to see if this interface is claimed, except for ctrl-requests with a type of
USB_TYPE_VENDOR.

When trying to use this device: http://www.akaipro.com/eiepro
redirected to a Windows vm running on qemu on top of Linux.

The windows driver makes a ctrl-req with USB_TYPE_CLASS and
USB_RECIP_ENDPOINT with index 0, and the mapping of the endpoint (0) to
the interface fails since ep 0 is the ctrl endpoint and thus never is
part of an interface.

This patch fixes this ctrl-req failing by skipping the checkintf call for
USB_RECIP_ENDPOINT ctrl-reqs on the ctrl endpoint.
