Subject: [PATCH 5.12 014/296] mtd: rawnand: txx9ndfmc: Fix external use of SW Hamming ECC helper

From: Miquel Raynal <miquel.raynal@...tlin.com>

commit 3d227a0b0ce319edbff6fd0d8af4d66689e477cc upstream.

Since the Hamming software ECC engine has been updated to become a
proper and independent ECC engine, it is now mandatory to either
initialize the engine before using any one of his functions or use one
of the bare helpers which only perform the calculations. As there is no
actual need for a proper ECC initialization, let's just use the bare
helper instead of the rawnand one.
