[PATCH v1 1/4] media: camss: vfe: Don't read hardware version needlessly

From: Robert Foss
Date: Mon Jul 26 2021 - 04:01:38 EST


vfe_set_power() is invoced a few times, which causes a lot of
VFE HW version prints.

Secondly there is no real reason for calling hw_version_read() from
this location specifically, since it does nothing more than print
the VFE HW version.

A better location for the hw_version_read() call would be somewhere
which is only executed once per VFE unit.
