KEY_RFKILL not found on kernel 2.6.30

KEY_RFKILL not found on kernel 2.6.30

[Keith Bannister]

I All,

I'm trying to compile compat-wireless on EasyPeasy (an Ubuntu 9.04
derivative for the eeepc)

The kernel headers are installed for my current kernel:

with

$ sudo apt-get install linux-headers-2.6.30.5-ep0

$ ls -l /lib/modules/`uname -r`/build
lrwxrwxrwx 1 root root 36 2010-03-04 12:02
/lib/modules/2.6.30.5-ep0/build ->
/usr/src/linux-headers-2.6.30.5-ep0/

I got the following compile error, after running

$ ./scripts/driver-select ath5k

$ make clean; make
make[1]: Entering directory `/usr/src/linux-headers-2.6.30.5-ep0'
  CLEAN   /home/keith/wireless/compat-wireless-2010-03-03

I ran into the same problem but was able to get around it by patching
include/linux/input.h. Details here: http://patchwork.kernel.org/patch/46630/

HTH,

The same happens on Linux 2.6.26.  I've just sent a patch for that.
Sorry, I should have credited you as the original reporter.
