From: Damien Cassou <damien.cas...@lifl.fr>
The various devm_ functions allocate memory that is released when a driver
detaches. This patch replaces the use of kzalloc by devm_kzalloc.
Additionally, this patch fixes a memory leak: some memory was allocated for
'panel' but not released when the subsequent call to setup_vsync fails.
