From 3f416961b0a5000bf5556de1a53cc3cf87a6e744 Mon Sep 17 00:00:00 2001 From: "Amruth G.P" Date: Mon, 29 Jul 2019 02:04:54 -0700 Subject: [PATCH] ice: Add input handlers for virtual channel handlers Move the assignment to local variables after validation. Remove unnecessary checks in ice_vc_process_vf_msg() as the respective functions are now performing the checks.
