i reported and fixed that bug a week ago, see the "drivers/media build
fix for modular builds" patch on lkml.

currently i've got 20 build fixes in my queue that are not yet upstream
as of today's -git - see them below.

Some of them are integrated into subsystem trees already and they are
all in the process of being reviewed and accepted or redone differently
by their respective maintainers.

config at:

http://redhat.com/~mingo/misc/config-Tue_Apr_29_15_00_47_CEST_2008.bad

the reason was a missing include file, and a dependency on a deprecated
(but still in use) VIDEO_V4L1_COMPAT API.

i suspect we dont want SRAT parsing when CONFIG_HAVE_ARCH_PARSE_SRAT

NR_NODE_MEMBLKS even in this case and just let the code fall back

I suspect this driver got its HZ definition from some implicit

the bug was that the driver uses GPIO functionality but only includes
the interface definitions for the CONFIG_MT9M001_PCA9536_SWITCH case,
which was not set in this config.

The fix is to include linux/gpio.h unconditionally. (this is a small
cleanup as well as it removes and #ifdef is more robust than an
inclusion of asm/gpio.h)

while generally most users will have PNP enabled, drivers can support
non-PNP build mode too - and most drivers implement it. That is typically
done by providing a dummy pnp_driver structure that will not probe anything.

The fallback routines in the driver will handle this dumber mode of
operation too.

This patch implements that. I have not tested whether this actually
works on real hardware so take care. It does resolve the build bug.

[ Another solution that is used by a few drivers is to exclude the driver
in the Kconfig if PNP is disabled, via "depends on PNP", but this would
limit the availability of the driver needlessly. ]

IMO, it's the reverse selection from sound to V4L that makes things
complicated. I believe it's better to fix it as a normal dependency.

How about the patch below?

Takashi

Fix kconfig dependency mess of fm801-tea575x

FM801-tea575x tuner has a reverse selection to V4L1 and this causes
dependency problem. The patch simplifies the dependency with a
normal depend on VIDEO_V4L1.

Subject: drivers/media build fix for modular builds
From: Ingo Molnar <mingo@elte.hu>
Date: Wed Apr 30 09:36:42 CEST 2008
fix build bug:

LD kernel/built-in.o
LD drivers/built-in.o
ld: drivers/media/built-in.o: No such file: No such file or directory

which happens if all media drivers are modular:

http://redhat.com/~mingo/misc/config-Wed_Apr_30_09_24_48_CEST_2008.bad

In that case there's no obj-y rule connecting all the built-in.o files and
the link tree breaks.

the fix is to add a guaranteed obj-y rule for the core vmlinux to build.
(which results in an empty object file if all media drivers are modular)

Subject: irda: !PNP support for drivers/net/irda/smsc-ircc2.c
From: Ingo Molnar <mingo@elte.hu>
Date: Sun May 04 00:12:12 CEST 2008
x86.git testing found this build bug on v2.6.26-rc1:

ERROR: "pnp_get_resource" [drivers/net/irda/smsc-ircc2.ko] undefined!
make[1]: *** [__modpost] Error 1
make: *** [modules] Error 2

the driver did not anticipate the case of !CONFIG_PNP which is rare but
still possible. Instead of restricting the driver to PNP-only in the
Kconfig space, add the (trivial) dummy struct pnp_driver that other
drivers use in the !PNP case. The driver itself can in theory be
initialized on !PNP too in certain cases, via smsc_ircc_legacy_probe().

Patch only minimally build tested, i dont have this hardware.

with the following config:

http://redhat.com/~mingo/misc/config-Sun_May__4_07_09_30_CEST_2008.bad

the reason is the duplicate definition of the sysfs_update_group()
inline function.

The duplication was a merge error: it was added via -mm by commit
v2.6.25-7262-g2850699, "sysfs: sysfs_update_group stub for CONFIG_SYSFS=n",
but shortly before that the same commit was already merged upstream via
the sysfs tree, with commit v2.6.25-7211-g1cbfb7a.

the reason is the .suspend callback - which is defined even in the case

Subject: video: cinergyT2 build fix
From: Ingo Molnar <mingo@elte.hu>
Date: Sun May 04 22:22:06 CEST 2008
x86.git testing found the following build bug:

drivers/built-in.o: In function `cinergyt2_probe':
cinergyT2.c:(.text+0xb6117): undefined reference to `input_allocate_device'
cinergyT2.c:(.text+0xb6230): undefined reference to `input_register_device'
cinergyT2.c:(.text+0xb623d): undefined reference to `input_free_device'

with the following config:

http://redhat.com/~mingo/misc/config-Sun_May__4_22_06_54_CEST_2008.bad

The reason for the bug is that the cinergyT2 driver depends on
CONFIG_INPUT functionality, but if INPUT is modular it's still
possible to build CONFIG_DVB_CINERGYT2=y - which leads to missing
symbols.

The solution is to make DVB_CINERGYT2 dependent on INPUT.

[ This solves the build problem - i have not tested the driver on this card. ]
