From 13497f58670c4e7a30170738f07b17d90011c785 Mon Sep 17 00:00:00 2001 From: Giuseppe CAVALLARO Date: Mon, 4 Jun 2012 06:36:22 +0000 Subject: [PATCH] stmmac: remove two useless initialisations This patch removes two useless initialisations in the stmmac_rx and stmmac_tx functions. In the former, the count variable was reset twice and in the stmmac_tx we only need to increment the dirty pointer w/o setting the entry variable. v2: review the subject and comment that was not clear in my first version.
