+Subject: ACPICA: Allow multiple backslash prefix in namepaths
+
+From: Lin Ming <ming.m.lin@intel.com>
+
+commit d037c5fd7367548191eab2b376a1d08c4ffaf7ff upstream.
+
+In a fully qualified namepath, allow multiple backslash prefixes.
+This can happen because of the use of a double-backslash in strings
+(since backslash is the escape character) causing confusion.
+ACPICA BZ 739 Lin Ming.
