Subject: [PATCH v3 06/13] net: ethernet: ti: cpsw: create common struct to hold shared driver data
Date: Wed, 10 Aug 2016 02:22:37 +0300	[thread overview]
Message-ID: <1470784964-26440-7-git-send-email-ivan.khoronzhuk@linaro.org> (raw)
In-Reply-To: <1470784964-26440-1-git-send-email-ivan.khoronzhuk@linaro.org>

This patch simply create holder for common data and as a start moves
pdev var to it.
