      USB: Support Blackberry Pearl with berry_charge · 49bb607f
      由 Jeremy Katz 提交于 
      The Blackberry Pearl (8100) needs similar tweaks as older Blackberry models
to be able to charge when connected via USB.  The Pearl also adds an
additional need to go into a separate mode for fully accessing the device;
do that by default as well.

      USB: prevent char device open/deregister race · d4ead16f
      由 Alan Stern 提交于 
      This patch (as908) adds central protection in usbcore for the
prototypical race between opening and unregistering a char device.
The spinlock used to protect the minor-numbers array is replaced with
an rwsem, which can remain locked across a call to a driver's open()
method.  This guarantees that open() and deregister() will be mutually
exclusive.

The private locks currently used in several individual drivers for
this purpose are no longer necessary, and the patch removes them.  The
following USB drivers are affected: usblcd, idmouse, auerswald,
legousbtower, sisusbvga/sisusb, ldusb, adutux, iowarrior, and
usb-skeleton.

As a side effect of this change, usb_deregister_dev() must not be
called while holding a lock that is acquired by open().  Unfortunately
a number of drivers do this, but luckily the solution is simple: call
usb_deregister_dev() before acquiring the lock.

In addition to these changes (and their consequent code
simplifications), the patch fixes a use-after-free bug in adutux and a
race between open() and release() in iowarrior.

      potential compiler error, irqfunc caller sites update · 0da2f0f1
      由 Yoann Padioleau 提交于 
      In 7d12e780 David Howells performed
this evolution:
 "IRQ: Maintain regs pointer globally rather than passing to IRQ handlers"

He correctly updated many of the function definitions that were using this
extra regs pointer parameter but forgot to update some caller sites of
those functions.  The reason the modifications was not properly done on all
drivers is that some drivers were rarely compiled because they are for
AMIGA, or that some code sites were inside #ifdefs where the option is not
set or inside #if 0.

Here is the semantic patch that found the occurences
and fixed the problem.

      backlight: Separate backlight properties from backlight ops pointers · 599a52d1
      由 Richard Purdie 提交于 
      Per device data such as brightness belongs to the indivdual device
and should therefore be separate from the the backlight operation
function pointers. This patch splits the two types of data and
allows simplifcation of some code.

      backlight: Fix external uses of backlight internal semaphore · 28ee086d
      由 Richard Purdie 提交于 
      backlight_device->sem has a very specific use as documented in the
header file. The external users of this are using it for a different
reason, to serialise access to the update_status() method.

backlight users were supposed to implement their own internal
serialisation of update_status() if needed but everyone is doing
things differently and incorrectly. Therefore add a global mutex to
take care of serialisation for everyone, once and for all.

Locking for get_brightness remains optional since most users don't
need it.

Also update the lcd class in a similar way.

      backlight: Remove unneeded owner field · dfcba200
      由 Richard Purdie 提交于 
      Remove uneeded owner field from backlight_properties structure.

Nothing uses it and it is unlikely that it will ever be used. The
backlight class uses other means to ensure that nothing references
unloaded code.

      USB: Driver to charge USB blackberry devices · df23fa01
      由 Greg Kroah-Hartman 提交于 
      A simple driver to turn on the charging capability of a USB BlackBerry
device when it is plugged into the machine.  It does not bind to the
device, so all userspace programs can still sync properly with it.

Note, if CONFIG_USB_SUSPEND is enabled, it can play havoc with this
device as the power to the port will be shut down.  This device id will
have to be added to the global blacklist table when it is created.

      [PATCH] remove many unneeded #includes of sched.h · cd354f1a
      由 Tim Schmielau 提交于 
      After Al Viro (finally) succeeded in removing the sched.h #include in module.h
recently, it makes sense again to remove other superfluous sched.h includes.
There are quite a lot of files which include it but don't actually need
anything defined in there.  Presumably these includes were once needed for
macros that used to live in sched.h, but moved to other header files in the
course of cleaning it up.

To ease the pain, this time I did not fiddle with any header files and only
removed #includes from .c-files, which tend to cause less trouble.

Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha,
arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig,
allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all
configs in arch/arm/configs on arm.  I also checked that no new warnings were
introduced by the patch (actually, some warnings are removed that were emitted
by unnecessarily included header files).
