[media] hdpvr: enable IR part
A number of things going on here, but the end result is that the IR part
on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or
lirc_zilog.
First up, there are some conditional build fixes that come into play
whether i2c is built-in or modular. Second, we're swapping out
i2c_new_probed_device() for i2c_new_device(), as in my testing, probing
always fails, but we *know* that all hdpvr devices have a z8 chip at
0x70 and 0x71. Third, we're poking at an i2c address directly without a
client, and writing some magic bits to actually turn on this IR part
(this could use some improvement in the future). Fourth, some of the
i2c_adapter storage has been reworked, as the existing implementation
used to lead to an oops following i2c changes c. 2.6.31.
Earlier editions of this patch have been floating around the 'net for a
while, including being patched into Fedora kernels, and they *do* work.
This specific version isn't yet tested, beyond loading ir-kbd-i2c and
confirming that it does bind to the RX address of the hdpvr.

#include <linux/i2c.h>

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files. percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability. As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that
only the necessary includes are there. ie. if only gfp is used,
gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include
blocks and try to put the new include such that its order conforms
to its surrounding. It's put in the include block which contains
core kernel includes, in the same order that the rest are ordered -
alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly
because the file doesn't have fitting include block), it prints out
an error message indicating which .h file needs to be added to the
file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly
over 4000 files, deleting around 700 includes and adding ~480 gfp.h
and ~3000 slab.h inclusions. The script emitted errors for ~400
files.
2. Each error was manually checked. Some didn't need the inclusion,
some needed manual addition while adding it to implementation .h or
embedding .c file was more appropriate for others. This step added
inclusions to around 150 files.
3. The script was run again and the output was compared to the edits
from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed.
e.g. lib/decompress_*.c used malloc/free() wrappers around slab
APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically
editing them as sprinkling gfp.h and slab.h inclusions around .h
files could easily lead to inclusion dependency hell. Most gfp.h
inclusion directives were ignored as stuff from gfp.h was usually
wildly available and often used in preprocessor macros. Each
slab.h inclusion directive was examined and added manually as
necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures
were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
distributed build env didn't work with gcov compiles) and a few
more options had to be turned off depending on archs to make things
build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config.
* powerpc and powerpc64 SMP allmodconfig
* sparc and sparc64 SMP allmodconfig
* ia64 SMP allmodconfig
* s390 SMP allmodconfig
* alpha SMP allmodconfig
* um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as
a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

[media] hdpvr: don't break long lines
Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.

[media] hdpvr: don't break long lines
Due to the 80-cols restrictions, and latter due to checkpatch
warnings, several strings were broken into multiple lines. This
is not considered a good practice anymore, as it makes harder
to grep for strings at the source code.
As we're right now fixing other drivers due to KERN_CONT, we need
to be able to identify what printk strings don't end with a "\n".
It is a way easier to detect those if we don't break long lines.
So, join those continuation lines.

[media] hdpvr: enable IR part
A number of things going on here, but the end result is that the IR part
on the hdpvr gets enabled, and can be used with ir-kbd-i2c and/or
lirc_zilog.
First up, there are some conditional build fixes that come into play
whether i2c is built-in or modular. Second, we're swapping out
i2c_new_probed_device() for i2c_new_device(), as in my testing, probing
always fails, but we *know* that all hdpvr devices have a z8 chip at
0x70 and 0x71. Third, we're poking at an i2c address directly without a
client, and writing some magic bits to actually turn on this IR part
(this could use some improvement in the future). Fourth, some of the
i2c_adapter storage has been reworked, as the existing implementation
used to lead to an oops following i2c changes c. 2.6.31.
Earlier editions of this patch have been floating around the 'net for a
while, including being patched into Fedora kernels, and they *do* work.
This specific version isn't yet tested, beyond loading ir-kbd-i2c and
confirming that it does bind to the RX address of the hdpvr.
