+[PATCH] vpu-lib: fix IOGetVirtMem return value checks
+
+When using a kernel where user/kernel split is 3G/1G, the address
+returned by IOGetVirtMem() can appear to be a negative int.
+
+IOSystemInit() incorrectly checks the return value of IOGetVirtMem().
+IOGetVirtMem() returns -1 on error (and not MAP_FAILED, nor any other
+negative value.)
+
+Fix that by correctly checking against -1 (and not MAP_FAILED!)
