[PATCH 5.10 564/663] media: ipu3-cio2: Fix mbus_code processing in cio2_subdev_set_fmt()

[Greg Kroah-Hartman]

From: Pavel Machek <pavel@xxxxxxx>

commit 334de4b45892f7e67074e1b1b2ac36fd3e091118 upstream.

Loop was useless as it would always exit on the first iteration. Fix
it with right condition.
