From f3f668b0ef4399b67e60e4c10a30099d630a6206 Mon Sep 17 00:00:00 2001 From: Andrzej Kaczmarek Date: Mon, 7 Nov 2011 17:19:04 -0200 Subject: [PATCH] Bluetooth: Use miliseconds for L2CAP channel timeouts Timers set by __set_chan_timer() should use miliseconds instead of jiffies. Commit 942ecc9c4643db5ce071562e0a23f99464d6b461 updated l2cap_set_timer() so it expects timeout to be specified in msecs instead of jiffies. This makes timeouts unreliable when CONFIG_HZ is not set to 1000. Signed-off-by: Andrzej Kaczmarek Signed-off-by: Gustavo F.
