5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>
[ Upstream commit c422b6a630240f706063e0ecbb894aa8491b1fa1 ]
STOP fallsthrough to WRITE_REQUESTED but this became problematic when
clearing the testunit registers was added to the latter. Actually, there
is no reason to clear the testunit state after STOP. Doing it when a new
WRITE_REQUESTED arrives is enough. So, no need to fallthrough, at all.
Fixes: b39ab96aa894 ("i2c: testunit: add support for block process calls")
