From ec917d77c57c0b3499442d2148bc4ca3598a5e8a Mon Sep 17 00:00:00 2001 From: Daniel Oakley Date: Thu, 16 Jun 2022 11:07:45 +0100 Subject: [PATCH] media: vimc: expand the names of vimc entity types When introducing the lens controller, it became apparent that the vimc entity type names were hard to understand, e.g. vimc_len_type refers to the lens. The names of the vimc entity types have been expanded to make the code easier to understand. There is no functional change intended.
