Subject: [ 10/12] SCSI: nsp32: use mdelay instead of large udelay constants
Date: Mon, 12 Aug 2013 23:35:45 -0700 [thread overview]
Message-ID: <20130813063521.079897423@linuxfoundation.org> (raw)
In-Reply-To: <20130813063520.285638946@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Arnd Bergmann <arnd@arndb.de>
commit b497ceb964a80ebada3b9b3cea4261409039e25a upstream.
ARM cannot handle udelay for more than 2 miliseconds, so we
should use mdelay instead for those.
