From 9db7720cca8f55a1e0c8d0dc1587e35dca50afbf Mon Sep 17 00:00:00 2001 From: Roel Kluin <12o3l@tiscali.nl> Date: Tue, 13 Nov 2007 03:16:17 -0800 Subject: [MYRI_SBUS]: Prevent that myri_do_handshake lies about ticks. With '<=' tick can be incremented up to 26, The last loop is redundant since even when 'softstate' becomes 'STATE_READY', 'if (tick > 25)' will still cause the function to return -1, Signed-off-by: Roel Kluin <12o3l@tiscali.nl> Signed-off-by: David S.
