From 5c9df5fed198ad8b967f33a1e11862f2a1d08bf7 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 4 Jul 2012 22:27:18 +0000 Subject: small cleanup in ax25_addr_parse() The comments were wrong here because "AX25_MAX_DIGIS" is 8 but the comments say 6. Also I've changed the "7" to "AX25_ADDR_LEN". Signed-off-by: Dan Carpenter Signed-off-by: David S.
