The original implementation of dequeuing a request in progress
is not correct. Change to use a correct process and also clean
up the related functions a little bit.

In order to support multiple SoC kernel image, compile-time dependency
on a specific SoC type should be avoided.
fsl_udc_clk_finalize is already protected by cpu_is_mx35(), so remove
the compile-time check for CONFIG_SOC_IMX35.

Fix the following build error:
CC [M] drivers/usb/gadget/fsl_mxc_udc.o
drivers/usb/gadget/fsl_mxc_udc.c: In function 'fsl_udc_clk_finalize':
drivers/usb/gadget/fsl_mxc_udc.c:98: error: implicit declaration of function 'readl'
drivers/usb/gadget/fsl_mxc_udc.c:100: error: implicit declaration of function 'writel'
This error is caused by the follwing commit:
(16fcb63: arm/imx: remove mx31_setup_weimcs( ) from mx31.h)
,which removed '#include <linux/io.h>' from mx31.h.
fsl_mxc_udc.c includes <mach/hardware.h>, which in turns includes mx31.h, so
that's the reason fsl_mxc_udc.c built fine previously.
Instead of relying on the indirect inclusion of the linux/io.h header file,
include it directly in fsl_mxc_udc.c.

Some ISO gadgets, like audio, has SYNC attribute as well as
USB_ENDPOINT_XFER_ISOC for their bmAttributes at ISO endpoint
descriptor. So, it needs to use usb_endpoint_xfer_isoc to judge
ISO XFER.

Several UDC drivers had a gadget driver's speed sanity check of the
form of:
driver->speed != USB_SPEED_HIGH
or:
driver->speed != USB_SPEED_HIGH && driver->speed != USB_SPEED_FULL
As more and more gadget drivers support USB SuperSpeed, driver->speed
may be set to USB_SPEED_SUPER and UDC driver should handle such gadget
correctly. The above checks however fail to recognise USB_SPEED_SUPER
as a valid speed.
This commit changes the two checks to:
driver->speed < USB_SPEED_HIGH
or:
driver->speed < USB_SPEED_FULL
respectively.

Currently the driver tries to save context in the suspend path, but
will cause an abort if the device is already runtime suspended. This
happens, for example, if MUSB loaded/compiled-in, in host mode, but no
USB devices are attached. MUSB will be runtime suspended, but then
attempting a system suspend will crash due to the context save
being attempted while the device is disabled.
On OMAP, as of v3.1, the driver's ->runtime_suspend() callback will be
called late in the suspend path (by the PM domain layer) if the driver
is not already runtime suspended, ensuring a full shutdown.
Therefore, the context save is not needed in the ->suspend() method
since it will be called in the ->runtime_suspend() method anyways
(similarily for resume.)
NOTE: this leaves the suspend/resume methods basically empty (with
some FIXMEs and comments, but I'll leave it to the maintainers
to decide whether to remove them.

The SigmaDSP firmware loader currently does not perform enough boundary size
checks when processing the firmware. As a result it is possible that a
malformed firmware can cause an out of bounds memory access.
This patch adds checks which ensure that both the action header and the payload
are completely inside the firmware data boundaries before processing them.

This is caused by dereferencing 'rdev' after device_unregister() in
the regulator_unregister() function. 'rdev' is freed by
device_unregister(), so it must not be dereferenced after this call.

To perform PHY calibration and set a different EA value by chip ID,
Whenever the NIC chip power on, ie booting or resuming, we need to
force HW to calibrate PHY parameter again, and also set a proper EA
value which gather from experiment.
Those procedures help to reduce compatible issues(NIC is unable to link

There is a potential integer overflow in do_insnlist_ioctl() if
userspace passes in a large insnlist.n_insns. The call to kmalloc()
would allocate a small buffer, leading to a memory corruption.
The bug was reported by Dan Carpenter <dan.carpenter@oracle.com>
and Haogang Chen <haogangchen@gmail.com>. The patch was suggested by
Ian Abbott <abbotti@mev.co.uk> and Lars-Peter Clausen <lars@metafoo.de>.

There is an integer overflow here that could cause memory corruption
on 32 bit systems.
insnlist.n_insns could be a very high value size calculation for
kmalloc() could overflow resulting in a smaller "insns" than
expected. In the for (i = 0; i < insnlist.n_insns; i++) {... loop
we would read past the end of the buffer, possibly corrupting memory
as well.

In comedi_fops, mmap_count is decremented at comedi_vm_ops->close but
it is not incremented at comedi_vm_ops->open. This may result in a negative
counter. The patch introduces the open method to keep the counter
consistent.
The bug was triggerd by this sample code:
mmap(0, ...., comedi_fd);
fork();
exit(0);

Interrupts must be disabled prior to calling usb_hcd_unlink_urb_from_ep.
If interrupts are not disabled, it can potentially lead to a deadlock.
The deadlock is readily reproduceable on a slower (ARM based) device
such as the TI Pandaboard.
