6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>
[ Upstream commit fea6b5ebb71a2830b042e42de7ae255017ac3ce8 ]
We should allow RXDMA only if the reset was really successful, so clear
the flag after the reset call.
Fixes: 0e864b552b23 ("i2c: rcar: reset controller is mandatory for Gen3+")
