ok, removed it, we'll see.

I also have the one below, of similar pattern. (so it's 8 fixlets, 
otherwise it's a vanilla kernel in this area)

x86.git randconfig testing found these build bugs in -git:

 drivers/media/video/stk-webcam.c: In function 'stk_create_sysfs_files':
 drivers/media/video/stk-webcam.c:340: error: implicit declaration of function 'video_device_create_file'
 drivers/media/video/stk-webcam.c: In function 'stk_remove_sysfs_files':
 [...]
 drivers/media/video/stk-webcam.c: In function 'v4l_stk_mmap':
 drivers/media/video/stk-webcam.c:846: error: 'VM_WRITE' undeclared (first use in this function)
 [...]

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.
