[PATCH 01/23] media: atomisp: get rid of phys event abstractions

From: Mauro Carvalho Chehab
Date: Tue Nov 16 2021 - 06:33:02 EST


ia_css_dequeue_event() is just an alias to ia_css_dequeue_psys_event(),
and atomisp_css_dequeue_event() do nothing but calling the event
dequeue logic.

Get rid of both abstractions, calling the function directly.
