Subject: [PATCH 08/29] ncr5380: Remove redundant AUTOSENSE macro
Date: Thu, 02 Oct 2014 16:56:36 +1000	[thread overview]
Message-ID: <20141002065630.166143919@telegraphics.com.au> (raw)
In-Reply-To: 20141002065628.256592712@telegraphics.com.au

[-- Attachment #1: ncr5380-remove-AUTOSENSE-macro --]
[-- Type: text/plain, Size: 11872 bytes --]

Every NCR5380 driver sets AUTOSENSE so it need not be optional (and the
mid-layer expects it). Remove this redundant macro to improve readability.
