Subject: [PATCH 10/14] dell-laptop: use dell_smbios_find_token() instead of find_token_location()
Date: Tue, 12 Jan 2016 15:02:56 +0100	[thread overview]
Message-ID: <1452607380-20861-11-git-send-email-kernel@kempniu.pl> (raw)
In-Reply-To: <1452607380-20861-1-git-send-email-kernel@kempniu.pl>

Replace all uses of find_token_location() with dell_smbios_find_token()
to avoid directly accessing the da_tokens table.
