From 638325154572ba2113a18669fe3b299caa2dabd9 Mon Sep 17 00:00:00 2001 From: Oliver Neukum Date: Wed, 7 Oct 2009 10:50:23 +0200 Subject: [PATCH] USB: serial: fix assumption that throttle/unthrottle cannot sleep many serial subdrivers are clearly written as if throttle/unthrottle cannot sleep. This leads to unneeded atomic submissions. This patch converts affected drivers in a way to makes very clear that throttle/unthrottle can sleep. Thus future misdesigns can be avoided and efficiency and reliability improved. This removes any such assumption using GFP_KERNEL and spin_lock_irq() Signed-off-by: Oliver Neukum Signed-off-by: Greg Kroah-Hartman --- Reading git-format-patch failed
