There's a race condition in stop_queue() in some drivers -
if drv_data->queue is empty, but drv_data->busy is still set
(or opposite situation) stop_queue will return -EBUSY.
So fix loop condition to check that both drv_data->queue is empty
and drv_data->busy is not set.
This patch affects following drivers:
pxa2xx_spi
spi_bfin5xx
amba-pl022
dw_spi

The pch_gpio_direction_output() function was missing a write to set the
desired output value. The function would properly set the GPIO
direction, but not the output value. The value would have to manually
be set with a follow up call to pch_gpio_set().
Add the missing write so that pch_gpio_direction_output() sets both the
GPIO direction and value.

If the device fails to respond, then the error path tries to remove an
interrupt that never got registered, which causes an backtrace from the
interrupt handling code.
Fix this by ensuring that the cleanup path has two labels and use the
correct path as needed.
fixes the following error:

In commit 13583b16592a ("PCI: refactor io size calculation code") Ram
had a thinko in the refactorization of the code: the end result used the
variable 'align' for the bus alignment, but the original code used
'min_align'.
Since then, another use of that 'align' variable got introduced by
commit c8adf9a3e873 ("PCI: pre-allocate additional resources to devices
only after successful allocation of essential resources.")
Fix both of those uses to use 'min_align' as they should.

We were allocating the size of the NVS file struct and not checking
whether the length of the buffer passed was correct before copying it
into the allocated memory. This is a security hole because buffer
overflows can occur if the userspace passes a bigger file than what is
expected.
With this patch, we check if the size of the data passed from
userspace matches the size required.
This bug was introduced in 2.6.36.

Patch removes the bogus flag introduced by upstream commit
eefdbec1ea8b7093d2c09d1825f68438701723cf. Old code had buffer length check
that new code tried to handle with URB_SHORT_NOT_OK flag. With USB debugging
enabled bogus flag caused usb_submit_urb fail.
Remove URB_SHORT_NOT_OK flag and add buffer length check to urb completion
handler.

When an interrupt occurs, the INT pin is driven low by the
MCP251x controller (falling edge) but in some cases the INT
pin can be connected to the MPU through a transistor or level
translator which inverts this signal. In this case interrupt
should be configured in rising edge.
This patch adds support to pass the IRQ flags via
mcp251x_platform_data.

The cio_ignore purge function is intended to only remove CCW devices
which are in the offline state. There is a time frame after the purge
function finished where a CCW device is scheduled for removal but
still accessible. When the device is set online during this time
frame, it may first appear online before it is then removed.
Fix this by preventing that CCW devices can be set online while there
is work (such as removal triggered by the purge function) for it
pending. Also ensure that the purge function does not schedule devices
for removal which are in the process of being set online.

Reorder the initialization sequence of the qdio module to avoid
writing to an uninitialized debug feature entry. Also reorder
the exit function to restore a consistent cleanup path.

Since 1c48a5c93da6313 (dt: Eliminate of_platform_{,un}register_driver)
mpc8xxx_wdt no longer builds as it tries to refer to a 'match' variable
rather than ofdev->dev.of_match that it checks just before.

The 11" Macbook Air appears to claim that its stride is 1366, when it's
actually 2048. Override it.

Some machines apparently give us bogus linelength/stride/pitch data, so
we need to support letting the DMI table override the supplied data.
I bet you can't guess whose machines I'm talking about.

It's expected that efifb will conflict with a native driver, so the
handover message should be informational rather than an error.

In practice this means enabling I2C (for DDC2) on all prosavage cards,
like the xorg ddx does. The savage4 and savage2000 families have only
one member each, so there is no change for those.

This patch fixes the checkpatch errors listed below:
ERROR: space required before the open parenthesis '('
ERROR: need consistent spacing around '+' (ctx:WxV)
ERROR: space prohibited before that close parenthesis ')'
Also, following warning is fixed by adding 'platid' variable
which can reduce number of lines exceeding 80 characters.
WARNING: line over 80 characters
