This is calling request_threaded_irq() but the thread parameter is NULL
so it's actually not a threaded irq.  Which is a bit misleading.  Call
request_irq() instead.

This change looks good, but it seems worth using devm_ call instead (as a 
separate patch probably). dsi->te_gpio is also requested per devm_ call, so 
eventually samsung_dsim_unregister_te_irq could be removed if the IRQ is 
device managed as well.

Despite that for this patch:
