USB: HCD: Add driver hooks for (un)?map_urb_for_dma

2011-02-08T23:18:16+00:00

Provide optional hooks for the host controller driver to override the
default DMA mapping and unmapping routines.  In general, these shouldn't
be necessary unless the host controller has special DMA requirements,
such as alignment contraints.  If these are not specified, the
general usb_hcd_(un)?map_urb_for_dma functions will be used instead.
Also, pass the status to unmap_urb_for_dma so it can know whether the
DMA buffer has been overwritten.

Finally, add a flag to be used by these implementations if they
allocated a temporary buffer so it can be freed properly when unmapping.

USB-BKL: Convert usb_driver ioctl to unlocked_ioctl

2010-08-10T21:35:35+00:00

And audit all the users. None needed the BKL.  That was easy
because there was only very few around.

Tested with allmodconfig build on x86-64

USB: remove unused usb_buffer_alloc and usb_buffer_free macros

Now that all callers are converted over, remove the compatibility
functions and all is good.

USB: remove usb_find_device

2010-05-20T20:21:45+00:00

Now on one uses this function and it seems useless,
so remove usb_find_device.

USB: simplify usb_sg_init()

2010-05-20T20:21:42+00:00

This patch (as1377) simplifies the code in usb_sg_init(), without
changing its functionality.  It also removes a couple of unused fields
from the usb_sg_request structure.

USB: Change the scatterlist type in struct urb

2010-05-20T20:21:41+00:00

Change the type of the URB's 'sg' pointer from a usb_sg_request to
a scatterlist.  This allows drivers to submit scatter-gather lists
without using the usb_sg_wait() interface.  It has the added benefit
of removing the typecasts that were added as part of patch as1368 (and
slightly decreasing the number of pointer dereferences).

USB: Add a usb_pipe_endpoint() convenience function

2010-05-20T20:21:41+00:00

Converting a pipe number to a struct usb_host_endpoint pointer is a little
messy.  Introduce a new convenience function to hide the mess.
