2. the cscope plugin expect a cscope.out.{in,po,};

There are three approach to solve it:
1. modify the cscope C code;
2. modify the cscope emacs plugin lisp code;
3. modify the Makefile;
I have tried to communicate with the cscope upstream, but later I
realize the third approach is most meaningful.

switch (cmd) {
case WDIOC_GETSUPPORT:
case WDIOC_GETSTATUS:
case WDIOC_GETBOOTSTATUS:
case WDIOC_GETTEMP:
case WDIOC_SETOPTIONS:
case WDIOC_KEEPALIVE:
case WDIOC_SETTIMEOUT:
case WDIOC_GETTIMEOUT:

device driver easier in the future.
This brings the watchdog drivers into line with coding style.
This patch takes cares of the indentation as described in chapter 1:

statement is to align the "switch" and its subordinate "case"
labels in the same column instead of "double-indenting" the "case"
labels.

[WATCHDOG] mpc8xxx_wdt: add support for MPC8xx watchdogs
The mpc8xxx_wdt driver is using two registers: SWSRR to push magic
numbers, and SWCRR to control the watchdog. Both registers are available
on the MPC8xx, and seem to have the same offsets and semantics as in
MPC83xx/MPC86xx watchdogs. The only difference is prescale value. So
this driver simply works on the MPC8xx CPUs.
One quirk is needed for the MPC8xx, though. It has small prescale value
and slow CPU, so the watchdog resets board prior to the driver has time to
load. To solve this we should split initialization in two steps: start
ping the watchdog early, and register the watchdog userspace interface
later.
MPC823 seem to be the first CPU in MPC8xx line, so we use fsl,mpc823-wdt
compatible matching.

MPC83xx CPUs are only differ in a way that watchdog could be disabled
once, but after it was enabled via software it becomes just the same as

Thus, to support MPC86xx I added the kernel timer which pings the watchdog
until the userspace opens it.

V4L/DVB (8609): media: Clean up platform_driver_unregister() bogosity.
So, platform_driver_unregister() doesn't actually have a return value,
nor do any of the void __exit routines. It's reassuring to know that
people copy and paste blindly. This completely blew up my compiler.

V4L/DVB (8607): cxusb: fix OOPS and broken tuning regression on FusionHDTV Dual Digital 4
quoting Robert Lowery:
I think I've found the cause of the oops.
[...]
BTW it appears I have fixed my tuning problems with the updated patch
below. This reverts a change Mauro made a while back.
All is good now :)
[...]
The good news is that I've got a better patch that definitely works this
time and even better, makes use of the standard firmware (rather than
the Australian specific one).

That regression was not root-caused by the original commit, it was just
uncovered by it, and the real fix was done by Alan Stern in commit 580da34847488b404218d1d7f53b156f245f5555 ("Fix USB storage hang on

We can thus re-introduce the change that was confirmed by Alan Jenkins
to be still required by his odd card reader.

Based upon original patch by Herbert Xu, which contained
the following problem description:
--------------------
When the forward delay is set to zero, we still delay the setting
of the forwarding state by one or possibly two timers depending
on whether STP is enabled. This could either turn out to be
instantaneous, or horribly slow depending on the load of the
machine.
As there is nothing preventing us from enabling forwarding straight
away, this patch eliminates this potential delay by executing the
code directly if the forward delay is zero.
The effect of this problem is that immediately after the carrier
comes on a port, the bridge will drop all packets received from
that port until it enters forwarding mode, thus causing unnecessary
packet loss.
Note that this patch doesn't fully remove the delay due to the
link watcher. We should also check the carrier state when we
are about to drop an incoming packet because the port is disabled.
But that's for another patch.
--------------------
This version of the fix takes a different approach, in that
it just does the state change directly.

an occasion to munmap and repeat. Okay, let's quieten the compiler (but I
would prefer it if pprev, rb_link and rb_parent were meaningful in that
case, rather than whatever's in them from descending the tree).

dma: fix order calculation in dma_mark_declared_memory_occupied()
get_order() takes byte-sized input, not a page-granular one.
Irrespective of this fix I'm inclined to believe that this doesn't work
right anyway - bitmap_allocate_region() has an implicit assumption of
'pos' being suitable for 'order', which this function doesn't seem to
enforce (and since it's being called with a byte-granular value there's no
reason to believe that the callers would make sure device_addr is passed
accordingly - it's also not documented that way).
