5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Val Packett <val@xxxxxxxxxxxx>
commit b27d8946b5edd9827ee3c2f9ea1dd30022fb1ebe upstream.
.setup_interface first gets called with a "target" value of
NAND_DATA_IFACE_CHECK_ONLY, in which case an error is expected
if the controller driver does not support the timing mode (NVDDR).
Fixes: a9ecc8c814e9 ("mtd: rawnand: Choose the best timings, NV-DDR included")
