usb: kill DEBUG compile option

2013-12-03T18:34:33+00:00

In the drivers that no longer need it, it is removed.
It is removed from the Makefile. Drivers not fully converted
to dynamic debug have it shifted down into the individual
drivers.

USB/host: Use existing macros instead of hard-coded values in uhci-debug.c

2013-10-06T00:58:48+00:00

Now that UHCI IO registers have been defined in uhci-hcd.h, use them.

USB: uhci: check buffer length to avoid memory overflow

2013-01-24T21:42:09+00:00

  for function uhci_sprint_schedule:
    the buffer len is MAX_OUTPUT: 64 * 1024, which may not be enough:
      may loop UHCI_NUMFRAMES times (UHCI_NUMFRAMES is 1024)
      each time of loop may get more than 64 bytes
    so need check the buffer length to avoid memory overflow

  this patch fix it like this:
    at first, make enough room for buffering the exceeding contents
    judge the contents which written whether bigger than buffer length
    if bigger (the exceeding contents will be in the exceeding buffer)
      break current work flow, and return.

USB: UHCI: Add support for big endian descriptors

2011-05-19T23:43:20+00:00

This patch adds support for universal host controllers that use
big endian descriptors. Support for BE descriptors requires a non-PCI
host controller. For kernels with PCI-only UHCI there should be no
change in behaviour.

This patch tries to replicate the technique used to support BE descriptors
in the EHCI HCD. Parts added to uhci-hcd.h are basically copy'n'paste from
ehci.h.

USB: UHCI: Wrap I/O register accesses

2011-05-07T01:24:01+00:00

This patch is part of a series that extend the UHCI HCD to support
non-PCI controllers.

This patch replaces in{b,w,l} and out{b,wl} with calls to local inline
functions. This is done so that the register access functions can be
extended to support register areas not mapped in PCI I/O space.

BKL: remove extraneous #include

2010-11-17T16:59:32+00:00

The big kernel lock has been removed from all these files at some point,
leaving only the #include.

Remove this too as a cleanup.

USB: remove fake "address-of" expressions

2010-08-10T21:35:45+00:00

Fake "address-of" expressions that evaluate to NULL generally confuse
readers and can provoke compiler warnings.  This patch (as1412)
removes three such fake expressions, using "#ifdef"s in their place.

USB-BKL: Remove BKL use in uhci-debug

2010-08-10T21:35:36+00:00

BKL was not really needed, just came from earlier push downs.

The only part that's a bit dodgy is the lseek function. Would
need another lock or atomic access to fpos on 32bit?
Better to have a libfs lseek
