From 8fd4bc8a15b218165c45f44eba1b33a3c7181dfb Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 1 Mar 2018 14:40:19 +0000 Subject: [PATCH] ieee802154: remove unused variable 'val' Variable 'val' is not being initialized and is later being logically or'd with DAR_PHY_CTRL4_PROMISCUOUS. Considering this variable is never being read anyway we may as well remove val altogether.
