From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 6b430c7595e4eb95fae8fb54adc3c3ce002e75ae ]
A successful 'init_rs_non_canonical()' call should be balanced by a
corresponding 'free_rs()' call in the error handling path of the probe, as
already done in the remove function.
Update the error handling path accordingly.
Fixes: 8c61b7a7f4d4 ("[MTD] [NAND] Use rslib for CAFÉ ECC")
