input: add MODALIAS to the event environment


Could you please tell me sample modaliases for a number of "common" devices (like a PS/2 mouse)?

I ask because earlier (namely, in http://www.kernel.org/pub/linux/kernel/people/gregkh/gregkh-2.6/old/gregkh-all-2.6.15.patch) such modaliases contained commas (",") and comma is not a "trusted" character in Udev (see replace_untrusted_chars() in udev_utils_string.c). Thus, such modaliases were mangled and didn't work.



Only if you read it with $sysfs{modalias}, it's available in $env{MODALIAS}
and does not get mangled there, right? If you have problems with that,
let us know and we will fix it.


With the old gregkh-all-2.6.15.patch, I have:

sh-3.1# cat /sys/class/input/input1/modalias
input:b0011v0002p0004e0000-e0,1,2,k110,111,112,113,114,r0,1,8,amlsfw
sh-3.1# echo "add" >/sys/class/input/input1/uevent
sh-3.1# cat /events/1663
PHYSDEVPATH=/devices/platform/i8042/serio0
EV=7
SUBSYSTEM=input
DEVPATH=/class/input/input1
NAME="GenPS/2 Genius <NULL>"
ACTION=add
PWD=/
UDEV_LOG=7
REL=103
KEY=1f0000 0 0 0 0 0 0 0 0
UDEVD_EVENT=1
SHLVL=1
PHYSDEVDRIVER=psmouse
PHYS="isa0060/serio1/input0"
PRODUCT=11/2/4/0
PHYSDEVBUS=serio
SEQNUM=1663
_=/usr/bin/env

i.e., there is the "modalias" file in sysfs but no $MODALIAS in the environment. Is this the problem that your patch solves (note: I haven't tried it yet)?
