From 2f91abd4516da0cadfb955c963b16f96e2e6c07a Mon Sep 17 00:00:00 2001 From: Denis ChengRq Date: Mon, 2 Jun 2014 01:18:01 -0700 Subject: [PATCH] genetlink: remove superfluous assignment the local variable ops and n_ops were just read out from family, and not changed, hence no need to assign back. Validation functions should operate on const parameters and not change anything. Signed-off-by: Cheng Renquan Signed-off-by: David S.
