--------------------------------

commit 8544cda9 upstream.

Reading ECC status is failing.

tx58cxgxsxraix_ecc_get_status() is using on-stack buffer
for SPINAND_GET_FEATURE_OP() output. It is not suitable
for DMA needs of spi-mem.

Fix this by using the spi-mem operations dedicated buffer
spinand->scratchbuf.

See
spinand->scratchbuf:
