[Intel-gfx] [PATCH] tests/drv_suspend: Replace "&> /dev/null" with "> /dev/null 2>&1"

[oscar.mateo at intel.com]

From: Oscar Mateo <oscar.mateo at intel.com>

Some shells do not understand "&>". For instance, my Ubuntu 12.04
machine has /bin/sh pointing to dash, which makes a mess out of
"&>" (to the point that the helper processes cannot be killed).
