This is due to the missing include of linux/usb/composite.h - this patch
adds the missing include.
In addition there's also a problem in fsg_common_init() where we memset
'common', but we use the size of a pointer to 'struct fsg_common' as the
size argument to memset(), not the actual size of the struct. This patch
fixes the sizeof so we zero the entire struct as intended.

There are a few error paths in ehci_hcd_omap_probe that can be triggered
because of memory allocation or hw failure. Change those dev_dbg error
prints to dev_err with an error code printed so that the end users are able
to notice the issue.

Gadget MUSB driver handles dma mappings in musb_gadget_queue(). Where as it is
possible for dma code to reject the usb request later at ->channel_program()
called from txstate()/rxstate()
For example ->channel_program in tusb6010_omap.c:
static int tusb_omap_dma_program(struct dma_channel *channel, u16 packet_sz,
u8 rndis_mode, dma_addr_t dma_addr, u32 len)
{
...
if (unlikely(dma_addr & 0x1) || (len < 32) || (len > packet_sz))
return false;
...
if (dma_addr & 0x2)
return false;
...
}
In this case, usb request will be handled in PIO mode which renders dma mapping
operations unnecessary.
This patch adds an api to allow dma code to indicate incompatibility with usb
request. Gadget musb driver call this api, if available, before dma mappings to
avoid any unnecessary mapping operations.

If dma buffers are mapped by a higher layer, with a boolean musb_request.mapped
it is still possible to call dma_sync_single_for_device() from
musb_g_giveback(), even if txstate()/rxstate() has called unmap_dma_buffer()
before falling back to pio mode.
Moreover, check for musb_ep->dma is moved within map_dma_buffer() so where
applicable checks for it are removed. And where possible, checks for
is_dma_capable() are merged with buffer map state check.

We know that blackfin doesn't support double
buffering feature as of today. So we add a
flag set by musb_platform_init() to forcefully
disable that feature.
Such flag is created and marked as deprecated
to force us to find a solution for the missing
double buffering support on blackfin.

use musb_read/writew instead of musb_read/writel and simply some format casts.

musb_probe() only regards 0 as a wrong IRQ number, despite platform_get_irq()
that it calls returns -ENXIO in that case. It leads to musb_init_controller()
calling request_irq() with a negative IRQ number, and when it naturally
fails, the following is printed to the console:
request_irq -6 failed!
musb_init_controller failed with status -19
Fix musb_probe() to filter out the error values as well as 0.

This patch fixes kernel panic during s2ram, which is caused
by the below:
- musb is not put into drv data of musb platform device if
CONFIG_USB_MUSB_HDRC_HCD is defined
- glue layer driver always get musb instance via platform_get_drvdata.
The patch fixes the issue by always puting musb into drv data
of musb platform device, which is doable even the platform device
is a host controller device.

The USB core keeps track of pending resume requests for root hubs, in
order to resolve races between wakeup requests and suspends. However
the code that does this is subject to another race (between wakeup
requests and resumes) because the WAKEUP_PENDING flag is cleared
before the resume occurs, leaving a window in which another wakeup
request might arrive.
This patch (as1447) fixes the problem by clearing the WAKEUP_PENDING
flag after the resume instead of before it.
This fixes Bugzilla #24952.

If anyone comes across a high-speed hub that (by mistake or by design)
claims to have no Transaction Translators, plugging a full- or
low-speed device into it will cause the USB stack to crash. This
patch (as1446) prevents the problem by ignoring such devices, since
the kernel has no way to communicate with them.

In drivers/usb/host/sl811-hcd.c::sl811h_urb_enqueue(), memory is allocated
with kzalloc() and assigned to 'ep'. If we leave via the 'fail' label due
to 'if (ep->maxpacket > H_MAXPACKET)', then 'ep' will go out of scope
without having been assigned to anything, so we'll leak the memory we
allocated.
This patch fixes the leak by simply calling kfree(ep); before jumping to
the 'fail' label.

The major and minor number saved in the product_info structure
were copied from the address instead of the data, causing an
inconsistency in the reported versions during firmware loading:
usb 4-1: firmware: requesting edgeport/down.fw
/usr/src/linux/drivers/usb/serial/io_edgeport.c: downloading firmware version (930) 1.16.4

/usr/src/linux/drivers/usb/serial/io_edgeport.c: FirmwareMajorVersion 0.0.4
This can cause some confusion whether firmware loaded successfully
or not.

The RX lock is used to protect the RX buffer from concurrent access in DMA
mode between the timer and RX interrupt routines. It is independent from
the uart lock which is used to protect the TX buffer. It is possible for
a uart TX transfer to be started up from the RX interrupt handler if low
latency is enabled. So we need to split the locks to avoid deadlocking in
this situation.
In PIO mode, the RX lock is not necessary because the handle_simple_irq
and handle_level_irq functions ensure driver interrupt handlers are called
once on one core.
And now that the RX path has its own lock, the TX interrupt has nothing to
do with the RX path, so disabling it at the same time.

Commit 728674a7e466628df2aeec6d11a2ae1ef968fb67 moved virtio_console.c
to drivers/tty/hvc/ under the perception of this being an hvc driver.
It was such once, but these days it has generic communication
capabilities as well, so move it to drivers/char/.
In the future, the hvc part from this file can be split off and moved
under drivers/tty/hvc/.

<20110127235214.GA5107@thialfi.dhcp.drexel.edu>", the ni_pcimio module
is missing module metadata, including a license.
This patch adds module metadata to all the NI comedi driver modules. It
also removes a duplicate MODULE_LICENSE("GPL") line from the "mite"
module.

Solved a locking issue that resulted in driver crashes with the 43224 and 43225
chips. The problem has been reported on several fora. Root cause was two fold:
hardware was being manipulated by two unsynchronized threads, and a scan
operation could interfere with an ongoing dynamic calibration process. Fix was
to invoke a lock on wl_ops_config() operation and to set internal flags when a
scan operation is started and stopped.
Please add this to the staging-linus branch.

The hv_netvsc gets RNDIS_STATUS_MEDIA_CONNECT event after the VM
is live migrated. Adding call to netif_notify_peers() for this event
to send GARP (Gratuitous ARP) to notify network peers. Otherwise,
the VM's network connection may stop after a live migration.
This patch should also be applied to stable kernel 2.6.32 and later.

Under harsh testing conditions, including low memory, the guest would

problems in the driver while performing these tests for extended periods
of time.

Some cases try to modify const strings, and in any event the

Currently, when rmmod pch_can, kernel failure occurs.
The cause is pci_iounmap executed before pch_can_reset.

Currently, 800k comms fails since prop_seg set zero.
