Combination of the following changes:

firedtv: reinstate debug logging option

    Henrik Kurelid tells me that FCP debug logging (which I removed during
    cleanups) is still useful when working on driver issues together with
    end users.  So bring it back in an updated form with only 60% of the
    original code footprint.

    Logging can be enabled with
    # echo -1 > /sys/module/firedtv/parameters/debug

    1 instead of -1 enables only FCP header logging,
    2 instead of -1 enables only hexdumps of the entire FCP frames.
    0 switches logging off again.

firedtv: build fix for INPUT=m and DVB_FIREDTV=y

Thu, 19 Feb 2009 20:40:39 +0100
firedtv: use msecs_to_jiffies

    Pointed out by Mauro Carvalho Chehab.

Sun Feb 15 20:50:46 CET 2009
firedtv: some more housekeeping

    Fix an old checkpatch warning and a new compiler warning.

Sun Feb 15 15:33:17 CET 2009
firedtv: rename a file once more

    At the moment, about a third of avc.c is specific to FireDTVs rather
    than generic AV/C code.  Rename it to firedtv-avc.c.

Sun Feb 15 15:33:17 CET 2009
firedtv: dvb demux: more compact channels backing store

    Replace struct firedtv_channel { bool active; int pid; } channel[16];
    by unsigned long channel_active; u16 channel_pid[16];.

Sun Feb 15 15:33:17 CET 2009
firedtv: dvb demux: some simplifications

    c->active was unnecessarily cleared twice.

    Also, by marking the channel inactive before the for loop,
    the loop becomes identical with fdtv_channel_collect().

Sun Feb 15 15:33:17 CET 2009
firedtv: dvb demux: remove a bogus loop

    This loop is unnecessary because
      - only active channel[].pid's will be sent to the device,
      - when a channel is activated, its pid is set to dvbdmxfeed->pid.

    Perhaps the original code was there because it was initially not fully
    covered by the fdtv->demux_mutex.

Sun Feb 15 15:33:17 CET 2009
firedtv: dvb demux: fix mutex protection

    fdtv_start_feed() accessed the channel list unsafely.
    Fully serialize it with itself and fdtv_stop_feed().

Sun Feb 15 15:33:17 CET 2009
firedtv: dvb demux: fix missing braces

    Original code was:
            ...
            case DMX_TS_PES_OTHER:
                    //Dirty fix to keep firesat->channel pid-list up to date
                    for(k=0;k<16;k++){
                            if(firesat->channel[k].active == 0)
                                    firesat->channel[k].pid =
                                            dvbdmxfeed->pid;
                                    break;
                    }
                    channel = firesat_channel_allocate(firesat);
                    break;
            default:
            ...

    Looks bogus in several respects. For now let's just add braces to the if
    because that seems to be what the author meant.

Sun Feb 15 15:33:17 CET 2009
firedtv: allow build without input subsystem

    !CONFIG_INPUT is very unlikely on systems on which firedtv is of
    interest.  But we can easily support it.

Sun Feb 15 15:33:17 CET 2009
firedtv: replace EXTRA_CFLAGS by ccflags

    The former are deprecated.
    The latter can depend on Kconfig variables.

Sun Feb 15 15:33:17 CET 2009
firedtv: concentrate ieee1394 dependencies

    Move the entire interface with drivers/ieee1394 to firedtv-1394.c.
    Move 1394-independent module initialization code to firedtv-dvb.c.

    This prepares interfacing with drivers/firewire.

Sun Feb 15 15:33:17 CET 2009
firedtv: amend Kconfig menu prompt

Sun Feb 15 15:33:17 CET 2009
firedtv: remove kernel version compatibility macro

Sun Feb 15 15:33:17 CET 2009
firedtv: combine header files

    avc.h and firedtv-*.h are small and currently not shared with other
    drivers, hence concatenate them all into firedtv.h.

Sun Feb 15 15:33:17 CET 2009
firedtv: misc style touch-ups

    Standardize on lower-case hexadecimal constants.  Adjust whitespace.
    Omit unnecessary pointer type casts and an unnecessary list head
    initialization.  Use dev_printk.

Wed Feb 11 21:21:04 CET 2009
firedtv: avc, ci: remove unused constants

Wed Feb 11 21:21:04 CET 2009
firedtv: avc: remove bitfields from read descriptor response operands

    Don't use bitfields in struct types of on-the-wire data.

Wed Feb 11 21:21:04 CET 2009
firedtv: avc: remove bitfields from DSD command operands

    Don't use bitfields in struct types of on-the-wire data.

Wed Feb 11 21:21:04 CET 2009
firedtv: avc: header file cleanup

    Remove unused constants and declarations.
    Move privately used constants into .c files.

Wed Feb 11 21:21:04 CET 2009
firedtv: avc: remove bitfields from FCP frame types

    Don't use bitfields in struct types of on-the-wire data.

    Also move many privately used constants from avc.h to avc.c
    and remove some unused constants.

Sun, 18 Jan 2009 16:30:00 +0100 (CET)
firedtv: avc: fix offset in avc_tuner_get_ts

    The parentheses were wrong.  It didn't matter though because this code
    only writes a 0 into an area which is already initialized to 0.

Sun, 18 Jan 2009 16:30:00 +0100 (CET)
firedtv: avc: reduce stack usage, remove two typedefs

    It is safe to share a memory buffer for command frame and response frame
    because the response data come in after the command frame was last used.

    Even less stack would be required if only the actual required frame size
    instead of the entire FCP register size was allocated.

    Also, rename the defined types AVCCmdFrm and AVCRspFrm to
    struct avc_command_frame and struct avc_response_frame.
    TODO:  Remove the bitfields in these types.

Sun, 18 Jan 2009 16:30:00 +0100 (CET)
firedtv: cmp: move code to avc

Sun, 18 Jan 2009 16:30:00 +0100 (CET)
firedtv: iso: move code to firedtv-1394

Sun, 18 Jan 2009 16:30:00 +0100 (CET)
firedtv: iso: remove unnecessary struct type definitions

Sun, 18 Jan 2009 16:30:00 +0100 (CET)
firedtv: iso: style changes and fixlets

    Add cleanup after failure in setup_iso_channel.
    Replace printk() by dv_err().
    Decrease indentation level in rawiso_activity_cb().
