From 4894ac6b6c25b2693dc21c611621dc9fd21f4090 Mon Sep 17 00:00:00 2001 From: Jose Abreu Date: Thu, 26 Oct 2017 09:51:33 +0100 Subject: net: stmmac: dwc-qos-eth: Fix typo in DT bindings parsing According to DT bindings documentation we are expecting a property called "snps,read-requests" but we are parsing instead a property called "read,read-requests". This is clearly a typo. Fix it. Signed-off-by: Jose Abreu Cc: Joao Pinto Cc: David S. Miller Cc: Giuseppe Cavallaro Cc: Alexandre Torgue Signed-off-by: David S.
