Subject: [PATCH tip/core/rcu 09/19] drm: Make drm_dp_mst_dsc_aux_for_port() safe for old compilers

From: "Paul E. McKenney" <paulmck@...nel.org>

Older compilers either want two extra pairs of curly braces around the
initializer for local variable desc, or they want a single pair of curly
braces with nothing inside.  Because current Linux-kernel practice favors
the latter, this commit makes it so.
