[PATCH] staging: make board support depend on CLKDEV_LOOKUP

[PATCH] staging: make board support depend on CLKDEV_LOOKUP

[Paul Gortmaker]

Building allmodconfig for arch/cris currently fails with:

drivers/built-in.o: In function `board_staging_register_clock':
drivers/staging/board/board.c:131: undefined reference to `clk_add_alias'
make: *** [vmlinux] Error 1

The clk_add_alias lives in drivers/clk/clkdev.c and that file
is only compiled for CONFIG_CLKDEV_LOOKUP, so it would seem
we need to add a dependency on that.

Thanks!

There seems to be another missing dependency on OF_IRQ:

drivers/built-in.o: In function `board_staging_gic_fixup_resources':
(.init.text+0x21c2): undefined reference to `irq_create_of_mapping'

[PATCH v2] staging: make board support depend on OF_IRQ and CLKDEV_LOOKUP

[Paul Gortmaker]

Building allmodconfig for arch/cris currently fails with:

drivers/built-in.o: In function `board_staging_register_clock':
drivers/staging/board/board.c:131: undefined reference to `clk_add_alias'
make: *** [vmlinux] Error 1

The clk_add_alias lives in drivers/clk/clkdev.c and that file
is only compiled for CONFIG_CLKDEV_LOOKUP, so it would seem
we need to add a dependency on that.

Geert also reported seeing this in his build coverage:

  There seems to be another missing dependency on OF_IRQ:

  drivers/built-in.o: In function `board_staging_gic_fixup_resources':
  (.init.text+0x21c2): undefined reference to `irq_create_of_mapping'

so we might as well fix that at the same time since it is
on the same line.

Just checking this didn't fall through the cracks, as its absence
causes several arch breakage on linux-next for several days now:

(.init.text+0xf968): undefined reference to `clk_add_alias'

 
x86:     http://kisskb.ellerman.id.au/kisskb/buildresult/12448913/
powerpc: http://kisskb.ellerman.id.au/kisskb/buildresult/12449785/
parisc:  http://kisskb.ellerman.id.au/kisskb/buildresult/12449940/

and possibly others I've missed.

Paul.

This problem is now seen in mainline.

Also affected: alpha:allmodconfig, mips:allmodconfig, s390:allmodconfig.

and applying the patch fixes the problem.
