From 91fe9ca74e8220f17e2fa71a92cda330857daac4 Mon Sep 17 00:00:00 2001 From: Pavel Roskin Date: Thu, 9 Apr 2009 21:41:05 -0400 Subject: orinoco: correct timeout logic in __orinoco_hw_set_tkip_key() If the value read from HERMES_RID_TXQUEUEEMPTY becomes 0 after exactly 100 readings, we wrongly consider it a timeout. Rewrite the clever while loop as a for loop that does the right thing and looks simpler. Reported by Juha Leppanen Signed-off-by: Pavel Roskin Signed-off-by: John W.
