Now that Alan Stern has cleaned up the usb serial driver registration,
we have the ability to create a module_usb_serial_driver macro to make
things a bit simpler, like the other *_driver macros created.

But, as we need two functions here, we can't reuse the existing
module_driver() macro, so we need to roll our own.

Here's a patch implementing module_usb_serial_driver() and it converts
the pl2303 driver to use it, showing a nice cleanup.

As Alan Stern pointed out this member has nothing to do with the Command
Status Wrapper (CSW) as specified by the Universal Serial Bus Mass
Storage Class Bulk-Only Transport rev 1.0. It defines the structure
without the additional 18 filler bytes and defines the total size of the
struct to exactly 13 bytes. Larger responses should be dropped. All
in-tree users use a defines instead of sizeof() of this struct as far I
can tell.

US_BULK_FLAG_IN is defined as 1 and not used. The USB storage spec says
that bit 7 of flags within CBW defines the data direction. 1 is DATA-IN
(read from device) and 0 is the DATA-OUT. Bit 6 is obselete and bits 0-5
are reserved.
This patch redefines the unsued define US_BULK_FLAG_IN from 1 to 1 << 7
aka 0x80 and replaces the obvious users. In a following patch the
storage gadget will use it as well.

drivers/usb/host/fsl-mph-dr-of.c: In function 'fsl_usb2_device_register':
drivers/usb/host/fsl-mph-dr-of.c:97: error: 'struct pdev_archdata'
has no member named 'dma_mask'

It has discussed at: http://www.spinics.net/lists/linux-usb/msg57302.html

For PowerPC, there is dma_mask at struct pdev_archdata, but there is
no dma_mask at struct pdev_archdata for ARM. The pdev_archdata is
related to specific platform, it should NOT be accessed by
cross platform drivers, like USB.

The code for pdev_archdata should be useless, as for PowerPC,
it has already gotten the value for pdev->dev.dma_mask at function
arch_setup_pdev_archdata of arch/powerpc/kernel/setup-common.c.

We had a user report that running setserial on /dev/ttyACM0 didn't work.
He pointed at an old patch by Oliver Neukum from 2008 that never went anywhere..
http://permalink.gmane.org/gmane.linux.usb.general/9236

I made some minor changes to get it to apply again, and got the user to retest on 3.1,
and he reported it worked for him. https://bugzilla.redhat.com/show_bug.cgi?id=787607

The diff below is against 3.3rc. The only difference between this and
the version the user tested is the removal of the if (!ACM_READY) test
Havard removed ACM_READY in 99823f45
I'm unclear if there's need for a different test in its place.

We must not allow the input buffer length to change while we're
shuffling the buffer contents.  We also mustn't clear the WDM_READ
flag after more data might have arrived.  Therefore move both of these
into the spinlocked region at the bottom of wdm_read().

When reading desc->length without holding the iuspin lock, use
ACCESS_ONCE() to ensure the compiler doesn't re-read it with
inconsistent results.
