+Subject: ar71xx: another fix to wndr3700_board_detect
+
+My last bugfix (r47538) introduced a new bug in wndr3700_board_detect
+(again...).
+
+Assigning the result of ar71xx_get_mtd_offset_size_format to the model
+variable before stripping of garbage using awk will cause all NUL bytes to
+be removed before awk is applied, leading to model strings like
+"NETGEAR WNDRMACv2NETGEAR", where a NUL byte after the v2 is supposed to
+terminate the string.
+
+Fix by calling ar71xx_get_mtd_offset_size_format twice, once piping to awk
+directly.
