Cannot build in 3.17+ kernels about lg4l

[Flu-Ger]

Seems this apperars since 3.17 (at least 3.16.5 doesn't have this line of code)

As far as I can understand it, the kernel devs don't like write permissions on devices for "others":
kernel.h:814

  /* Other writable?  Generally considered a bad idea. */   \
  BUILD_BUG_ON_ZERO((perms) & 2) +              \
  (perms))`

Therefore all DEVICE_ATTR( calls could have 0660 instead of 0666 permitions. It could make sense to change the devicegroup to something like video?

Not bad idea, some device drivers (as nvidia nouveau) use video group.

The gnome15 project sets up appropriate permissions for devices using udev rules. I will look for other examples in the kernel code on how to set the defaults. If any of you has a patch ready, please attach it.

Should be solvet by commit 91b0a91
