Subject: [patch 20/28] input: Remove BKL from hp_sdc_rtc
References: <20091010153314.827301943@linutronix.de>
Content-Disposition: inline; filename=hp-sdc-rtc-remove-bkl.patch
Sender: linux-kernel-owner@vger.kernel.org
Content-Length: 1224
Lines: 38

cycle_kernel_lock() was added during the big BKL pushdown. It should
ensure the serializiation against driver init code. In this case there
is nothing to serialize. Remove it.
