[v2,03/31] media: xilinx-vipp: Clean up bound async notifier callback

Commit Message

Sakari Ailus May 16, 2023, 9:54 a.m. UTC

The async notifier bound callback does a lot of checks that have probably
been always unnecessary. Remove the lookup of the async connection that we
already have, as well as the debug print that is already printed by the
framework.
