    ixp4xx-beeper: add MODULE_ALIAS · 589499c0
    Alessandro Zummo authored
    The following patch allows ixp4xx-beeper to be loaded by udev
    automatically when compiled as a module with kernel versions 2.4.24 and
    greater.
    
    This patch is required because 43cc71ee
    ("platform: prefix MODALIAS with "platform:"") changed the modalias
    string to have the extra prefix.
    
    LKG7102D7:~# udevinfo -a -p /sys/devices/platform/ixp4xx-beeper.4
    
     looking at device '/devices/platform/ixp4xx-beeper.4':
       KERNEL=="ixp4xx-beeper.4"
       SUBSYSTEM=="platform"
       DRIVER==""
       ATTR{modalias}=="platform:ixp4xx-beeper"
    
    udev therefore tries to modprobe platform:ixp4xx-beeper instead of
    ixp4xx-beeper.
    
    LKG7102D7:~# udevtest /sys/devices/platform/ixp4xx-beeper.4
    ...
    import_uevent_var: import into environment: 'PHYSDEVBUS=platform'
    import_uevent_var: import into environment: 'MODALIAS=platform:ixp4xx-beeper'
    main: looking at device '/devices/platform/ixp4xx-beeper.4' from
    subsystem 'platform'
    wait_for_sysfs: file '/sys/devices/platform/ixp4xx-beeper.4/bus'
    appeared after 0 loops
    main: run: 'socket:/org/kernel/udev/monitor'
    main: run: '/sbin/modprobe --use-blacklist platform:ixp4xx-beeper'
    
    With this patch, depmod adds an alias line (see below) to
    modules.alias which allows modprobe to load the right module.
