Use a switch .. case .. would be easier to read.

Would it be better to use some macro or enums for the magic numbers?

The change is irrelevant to this patch.

The change shouldn't be in this patch.  Instead, another patch that
adds the mtk_vdec_comp_init_irq() invocation.

Remove the extra space before "*ctx".
