From 828e1b0b4c5eef96a7f9a64010532263430e1f13 Mon Sep 17 00:00:00 2001 From: Deepak Rawat Date: Wed, 5 Jun 2019 10:46:47 -0700 Subject: [PATCH] winsys/drm: Fix out of scope variable usage In this particular instance, struct member were used outside of the block where it was defined. Fix this by moving the definition outside of block.
