+Subject: ar71xx: fix wndr3700_board_detect for some NETGEAR WNDR3700v2 (again)
+
+When fixing the model string for WNDR3700v2 which contain a model string
+followed by 0xff in r46455, the match for other versions of the WNDR3700v2
+which just contain lots of 0xff broke (as the 0xff $model is checked for
+is stripped off).
+
+Fix by stripping off non-printable characters only for the actual output
+string, but not for the internal matching.
