Entrypoint cannot handle external mysql server running in non-standard port

[hulttis]

mysql_running () {
if [ "$remoteDB" -eq "1" ]; then
mysqladmin ping -u${ZM_DB_USER} -p${ZM_DB_PASS} -h${ZM_DB_HOST} > /dev/null 2>&1
else
mysqladmin ping > /dev/null 2>&1
fi
local result="$?"
if [ "$result" -eq "0" ]; then
echo "1" # mysql is running
else
echo "0" # mysql is not running
fi
}

According to the zm.conf ZM_DB_HOST can be ip:port - the mysql_running doesn't handle this situation correctly and mysqladmin ping fails.
should be f.ex;
mysqladmin ping -u${ZM_DB_USER} -p${ZM_DB_PASS} -h${ZM_DB_HOST} -P${ZM_DB_PORT}> /dev/null 2>&1

ZoneMinder database hostname or ip address and optionally port or unix socket

Acceptable formats include hostname[:port], ip_address[:port], or localhost:unix_socket

ZM_DB_HOST="192.168.100.16:3307"
