Subject: [PATCH 22/29] iwlwifi: add iwl_set_bits_mask
Date: Wed, 6 Jun 2012 15:22:03 +0200 [thread overview]
Message-ID: <1338988930-11561-22-git-send-email-johannes@sipsolutions.net> (raw)
In-Reply-To: <1338988930-11561-1-git-send-email-johannes@sipsolutions.net>
From: Johannes Berg <johannes.berg@intel.com>
In a few cases we need to set a value in
a certain mask inside a register, add the
function iwl_set_bits_mask() to make such
code easy.
