ixp4xx-beeper: add MODULE_ALIAS
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 43cc71eed1250755986da4c0f9898f9a635cb3bf ("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. alias platform:ixp4xx-beeper ixp4xx-beeper Signed-off-by: Gordon Farquharson <gordonfarquharson@gmail.com> Signed-off-by: Alessandro Zummo <a.zummo@towertech.it> Cc: Kay Sievers <kay.sievers@vrfy.org> Cc: David Brownell <david-b@pacbell.net> Cc: Atsushi Nemoto <anemo@mba.ocn.ne.jp> Cc: Greg Kroah-Hartman <gregkh@suse.de> Cc: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
