4.19-stable review patch. If anyone has any objections, please let me know. ------------------ From: Maxim Korotkov <korotkov.maxim.s@xxxxxxxxx> [ Upstream commit 6819db94e1cd3ce24a432f3616cd563ed0c4eaba ] The function hynix_nand_rr_init() should probably return an error code. Judging by the usage, it seems that the return code is passed up the call stack. Right now, it always returns 0 and the function hynix_nand_cleanup() in hynix_nand_init() has never been called.
