USB: ohci whitespace/comment fixups
This is an OHCI cleanup patch ... it removes a lot of erroneous whitespace (space before tab, at end of line) as well as the obsolete inline changelog. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

|

* OHCI is the main "non-Intel/VIA" standard for USB 1.1 host controller
|
||||
* interfaces (though some non-x86 Intel chips use it). It supports
|
||||
* smarter hardware than UHCI. A download link for the spec available
|
||||
* through the http://www.usb.org website.
|
||||
*
|
||||
* History:
|
||||
*
|
||||
* 2004/03/24 LH7A404 support (Durgesh Pattamatta & Marc Singer)
|
||||
* 2004/02/04 use generic dma_* functions instead of pci_* (dsaxena@plexity.net)
|
||||
* 2003/02/24 show registers in sysfs (Kevin Brosius)
|
||||
*
|
||||
* 2002/09/03 get rid of ed hashtables, rework periodic scheduling and
|
||||
* bandwidth accounting; if debugging, show schedules in driverfs
|
||||
* 2002/07/19 fixes to management of ED and schedule state.
|
||||
* 2002/06/09 SA-1111 support (Christopher Hoover)
|
||||
* 2002/06/01 remember frame when HC won't see EDs any more; use that info
|
||||
* to fix urb unlink races caused by interrupt latency assumptions;
|
||||
* minor ED field and function naming updates
|
||||
* 2002/01/18 package as a patch for 2.5.3; this should match the
|
||||
* 2.4.17 kernel modulo some bugs being fixed.
|
||||
*
|
||||
* 2001/10/18 merge pmac cleanup (Benjamin Herrenschmidt) and bugfixes
|
||||
* from post-2.4.5 patches.
|
||||
* 2001/09/20 URB_ZERO_PACKET support; hcca_dma portability, OPTi warning
|
||||
* 2001/09/07 match PCI PM changes, errnos from Linus' tree
|
||||
* 2001/05/05 fork 2.4.5 version into "hcd" framework, cleanup, simplify;
|
||||
* pbook pci quirks gone (please fix pbook pci sw!) (db)
|
||||
*
|
||||
* 2001/04/08 Identify version on module load (gb)
|
||||
* 2001/03/24 td/ed hashing to remove bus_to_virt (Steve Longerbeam);
|
||||
pci_map_single (db)
|
||||
* 2001/03/21 td and dev/ed allocation uses new pci_pool API (db)
|
||||
* 2001/03/07 hcca allocation uses pci_alloc_consistent (Steve Longerbeam)
|
||||
*
|
||||
* 2000/09/26 fixed races in removing the private portion of the urb
|
||||
* 2000/09/07 disable bulk and control lists when unlinking the last
|
||||
* endpoint descriptor in order to avoid unrecoverable errors on
|
||||
* the Lucent chips. (rwc@sgi)
|
||||
* 2000/08/29 use bandwidth claiming hooks (thanks Randy!), fix some
|
||||
* urb unlink probs, indentation fixes
|
||||
* 2000/08/11 various oops fixes mostly affecting iso and cleanup from
|
||||
* device unplugs.
|
||||
* 2000/06/28 use PCI hotplug framework, for better power management
|
||||
* and for Cardbus support (David Brownell)
|
||||
* 2000/earlier: fixes for NEC/Lucent chips; suspend/resume handling
|
||||
* when the controller loses power; handle UE; cleanup; ...
