[lvm-devel] [PATCH] Fix dmeventd path check



Hi,

I found a small bug in _start_server in daemons/dmeventd/libdevmapper-event.c: 

There is a possibility to change dmeventd_path by setting "executable"
parameter in config. But it will not work if there is no executable at
default DMEVENTD_PATH due to error in check: we must check args[0]
(which is dmeventd_path ? : default_dmeventd_path) instead of
DMEVENTD_PATH for existence. My patch fix this small issue.
