Subject: linux-next: build failure after merge of the final tree (v4l-dvb
 tree related)

Hi Mauro,

After merging the final tree, today's linux-next build (powerpc
allyesconfig) failed like this:

drivers/media/video/cx231xx/cx231xx-417.c: In function 'cx231xx_load_firmware':
drivers/media/video/cx231xx/cx231xx-417.c:943: error: implicit declaration of function 'vmalloc'
drivers/media/video/cx231xx/cx231xx-417.c:943: warning: cast to pointer from integer of different size
drivers/media/video/cx231xx/cx231xx-417.c:950: warning: cast to pointer from integer of different size
drivers/media/video/cx231xx/cx231xx-417.c:1039: error: implicit declaration of function 'vfree'

Caused by commit e0bb3704be9decb10985b0886031e76a228b5f32 ("[media]
cx231xx: Added support for Carraera, Shelby, RDx_253S and VIDEO_GRABBER").

Also, I don't think Arnd is going to like the new BKL usage also
introduced by the commit.  ;-)

I added the following patch for today:

Subject: [PATCH] v4l-dvb: using vmalloc needs vmalloc.h in cx231xx-417.c

Fixes these build errors and warnings:

drivers/media/video/cx231xx/cx231xx-417.c:943: error: implicit declaration of function 'vmalloc'
