The array size calculation in pvr_vm_mips_fini() appears to be incorrect based
on
taking the size of the pointer rather than the size of the array, which

When using the DSI interface via DSI2LVDS bridge, it seems a bit harsh
to reguire the requested and the actual px clock to be within
50Hz. A typical LVDS display requires the px clock to be within +-10%.
In case for HDMI .5% tolerance is required.
