The driver calls pci_set_mwi to enable memory-write-invalidate when it
is initialized, but does not call pci_clear_mwi when it is removed. Many
other drivers calls pci_clear_mwi when pci_set_mwi is called, such as
r8169, 8139cp and e1000.

This patch adds a function "ehci_pci_remove" to remove the pci driver.
This function calls pci_clear_mwi and usb_hcd_pci_remove, which can
fix the problem.

The default value for the 'transceiver select' field of
the PORTSC register may not always be correct. Previously
the phy-msm-usb driver would do this for us, but since
ehci-msm can now be instantiated standalone without any PHY
driver, the register needs to be explicitly initialized to
ULPI mode to properly communicate with the PHY.

This is not readily apparent, as firmware or bootloader code
also happen to pre-initialize this for us. However, it can
manifest when performing a driver unbind/rebind as follows:

 cd /sys/bus/platform/drivers/msm_hsusb_host
 echo QCOM8040:00 > unbind
 echo QCOM8040:00 > bind

The EHCI core executes a controller reset as part of this,
and as a result the register in question would revert to
its default state and must be re-initialized properly.
Furthermore this may be useful in the future when adding
PM suspend/resume support.

Currently the EHCI MSM driver has a hard dependency to be created
by an OTG layer, namely the phy-msm-usb driver. In some cases or

kbasename() helper is dedicated to find a last part of the filename or

Replace some lines of code by kbasename() call.

The current users do not have trailing slash and we are on the safe side to
make such change. I dig a history of the code under question up and found the
patch [1] that brought it along with the same to tty layer. The check for
trailing slash looks like copy'n'paste thing and I consider it as redundant.

This adds support for the interrupt controller present on PIC32 class
devices. It handles all internal and external interrupts. This controller
exists outside of the CPU core and is the arbitrator of all interrupts
(including interrupts from the CPU itself) before they are presented to
the CPU.

The following features are supported:
 - DT properties for EVIC and for devices/peripherals that use interrupt lines
 - Persistent and non-persistent interrupt handling
 - irqdomain and generic chip support
 - Configuration of external interrupt edge polarity

it does not have to warn about it.

If the parameter given to the macro is replaced throughout the macro as
it is evaluated.  The intent is that the macro parameter should replace
the only the first parameter to container_of().  However, the way the
macro was written, it would also inadvertantly replace a structure field
name.  If a parameter of any other name is given to the macro, it will
fail to compile, if the structure does not contain a field of the same
name.  At worst, it will compile, and hide improper access of an
unintended field in the structure.

Change the macro parameter name, so it does not conflict with the
structure field name.
