Subject: [PATCH 12/20] e1000: Consolidate Microwire EEPROM init code
Date: Sun, 17 Jan 2016 19:52:33 -0800	[thread overview]
Message-ID: <1453089161-6697-12-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1453089161-6697-1-git-send-email-andrew.smirnov@gmail.com>

All of the chips that bitbang Microwire to access EEPROM appear to be
configured in the same way, so move common code into a separate
function and make use of it.
