[Bug 881158] [NEW] findkeyboards does not find Samsung N150 keyboard

Public bug reported:

udev version is 173-0ubuntu4 on Ubuntu 11.10.

When I run /lib/udev/findkeyboards, the output is:
AT keyboard: no device node found

I expected the output to be:
AT keyboard: input/event4

The udevadm trigger command in the findkeyboards script finds two
devices:

$ udevadm trigger --dry-run --verbose --property-match=ID_INPUT_KEYBOARD=1
/sys/devices/platform/i8042/serio0/input/input4
/sys/devices/platform/i8042/serio0/input/input4/event4

The /devices/platform/i8042/serio0 parent device has the atkbd DRIVER.

When the script runs the following command for the first device, the
command fails with exit status 5.

$ udevadm info --query name --path=/sys/devices/platform/i8042/serio0/input/input4
no device node found
$ echo $?
5

It appears that the -e option on the first line of the script causes the
script to exit before the script can query the second device, which
would be successful if it got that far:

$ udevadm info --query name --path=/sys/devices/platform/i8042/serio0/input/input4/event4
input/event4
