Stefan Richter 612262a533 firesat: copyrights, rename to firedtv, API conversions, fix remote control input 
Combination of the following changes:

Tue, 26 Aug 2008 00:17:30 +0200 (CEST)
firedtv: fix remote control input

    and update the scancode-to-keycode mapping to a current model.  Per
    default, various media key keycodes are emitted which closely match what
    is printed on the remote.  Userland can modify the mapping by means of
    evdev ioctls.  (Not tested.)

    The old scancode-to-keycode mapping is left in the driver but cannot be
    modified by ioctls.  This preserves status quo for old remotes.

firedtv: replace tasklet by workqueue job

    Non-atomic context is a lot nicer to work with.

Sun, 24 Aug 2008 23:30:00 +0200 (CEST)
firedtv: move some code back to ieee1394 core

    Partially reverts "ieee1394: remove unused code" of Linux 2.6.25.

firedtv: replace semaphore by mutex

    firesat->avc_sem and ->demux_sem have been used exactly like a mutex.
    The only exception is the schedule_remotecontrol tasklet which did a
    down_trylock in atomic context.  This is not possible with
    mutex_trylock; however the whole remote control related code is
    non-functional anyway at the moment.  This should be fixed eventually,
    probably by turning the tasklet into a worqueue job.

    Convert everything else from semaphore to mutex.

    Also rewrite a few of the affected functions to unlock the mutex at a
    single exit point, instead of in several branches.

Sun, 24 Aug 2008 23:28:45 +0200 (CEST)
firedtv: some header cleanups

    Unify #ifndef/#define/#endif guards against multiple inclusion.
    Drop extern keyword from function declarations.
    Remove #include's into header files where struct declarations suffice.

    Remove unused ohci1394 interface and related unused ieee1394 interfaces.

    Add a few missing #include's and remove a few apparently obsolete ones.
    Sort them alphabetically.

Sun, 24 Aug 2008 23:27:45 +0200 (CEST)
firedtv: nicer registration message and some initialization fixes

    Print the correct name in dvb_register_adapter().

    While we are at it, replace two switch cascades by one for loop, remove
    a superfluous member of struct firesat and of two unused arguments of
    AVCIdentifySubunit(), and fix bogus kfree's in firesat_dvbdev_init().

Tue, 26 Aug 2008 14:24:17 +0200 (CEST)
firesat: rename to firedtv

    Suggested by Andreas Monitzer.  Besides DVB-S/-S2 receivers, the driver
    also supports DVB-C and DVB-T receivers, hence the previous project name
    is too narrow now.

    Not yet done:  Rename source directory, files, types, variables...

Sun, 24 Aug 2008 23:26:23 +0200 (CEST)
firesat: add missing copyright notes

    Reported by Andreas Monitzer and Christian Dolzer.
