udevtrigger: check presence of dev attribute
The presence of the 'uevent' attribute file does not always mean that a corresponding device node can be created under '/dev'. For valid device nodes, a 'dev' attribute file must be present which cntains the major and minor numbers of the device. Modify the code to check the presence of the dev attribute as well. This allows to avoid superfluous trigger_uevent calls. On a test system, the patch reduced the number of the triegger_uevent calls from 144 to 70. Signed-off-by: Gabor Juhos <juhosg@openwrt.org>
