           Summary: F5 and F6 keys on Macbook Air (and possibly other
                    macbooks)
           Product: Drivers
           Version: 2.5
     KernelVersion: v2.6.26-rc7
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Input Devices
        AssignedTo: drivers_input-devices at kernel-bugs.osdl.org
        ReportedBy: rydberg at euromail.se


Latest working kernel version: unknown
Earliest failing kernel version: unknown
Distribution: ubuntu hardy
Hardware Environment: macbook air
Software Environment: kernel source from git tree
Problem Description: hid-input.c contains no mapping for F5 and F6 keys

Steps to reproduce: none

Being a complete newcomer to kernel work, this might have other solutions
(based on quirks?), but here it is anyway:

In drivers/hid/hid-input.c, the apple_fn_keys translation table contains no
entries for the F5 and F6 keys, and the FN+F3 key is mysteriously mapped to
FN_F5. A patch is attached which maps the F5 and F6 keys to KBDILLUMDOWN and
UP, respektively, which make them work as keyboard backlight control keys.
Again, please note that this is only checked on the macbook air, and if there
are other means of solving this, please disregard the patch.
