Subject: i2c: rcar: clear NO_RXDMA flag after resetting
X-Git-Tag: microblaze-v6.13~756^2^2~1

i2c: rcar: clear NO_RXDMA flag after resetting

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+")
