From ae7871cc3ee8aebb6750d3dbac5a07119c43b4c2 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Thu, 27 Jun 2024 13:14:47 +0200 Subject: [PATCH] i2c: testunit: don't erase registers after STOP [ 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.
