[PATCH] (9/42) seeq8005

Based on viro NE33-seeq8005
	* switched seeq8005 to dynamic allocation
	* seeq8005: embedded ->priv
	* seeq8005: fixed resource leaks on failure exits
	* seeq8005: fixed clobbering on autoprobe
	* seeq8005: fixed jiffies truncation
	* seeq8005: fixed a typo in Kconfig - module is _not_ called ewrk3
