From f75268cd6cbd24e6c70ff1390f4de5d0bb618539 Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 6 Sep 2005 15:49:39 -0700 Subject: [AX25]: Make ax2asc thread-proof Ax2asc was still using a static buffer for all invocations which isn't exactly SMP-safe. Change ax2asc to take an additional result buffer as the argument. Change all callers to provide such a buffer. Signed-off-by: Ralf Baechle DL5RB Signed-off-by: David S.
