From f9ebd1bb41031afc162e9acda7ad044a35bccf82 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Fri, 7 Sep 2018 00:38:39 +0200 Subject: mtd: rawnand: Deprecate ->erase() The ->erase() hook have been overloaded by some drivers for bad reasons: either the driver was not fitting in the NAND framework and should have been an MTD driver (docg4), or the driver uses a specific path for the ERASE operation (denali), instead of implementing it generically. In any case, we should discourage people from overloading this method and encourage them to implement ->exec_op() instead. Move the ->erase() hook to the nand_legacy struct to make it clear.
