We forgot one call site directly using drm->dev_private.
This leads to a crash like this:
8<--- cut here ---
Unable to handle kernel NULL pointer dereference at virtual address 00000918
pgd = (ptrval)
[00000918] *pgd=00000000
Internal error: Oops: 5 [#1] SMP ARM
Modules linked in:
CPU: 0 PID: 1 Comm: swapper/0 Not tainted 5.7.0-15001-gfa384b50b96b-dirty #514
Hardware name: ST-Ericsson Ux5x0 platform (Device Tree Support)
PC is at mcde_display_enable+0x78/0x7c0
LR is at mcde_display_enable+0x78/0x7c0
Fix this by using to_mcde() as in other functions.
