From e7bfb3fdbde3bfeeeb64e2d73ac6babe59519c9e Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Mon, 12 Feb 2018 22:03:11 +0100 Subject: mtd: Stop updating erase_info->state and calling mtd_erase_callback() MTD users are no longer checking erase_info->state to determine if the erase operation failed or succeeded. Moreover, mtd_erase_callback() is now a NOP. We can safely get rid of all mtd_erase_callback() calls and all erase_info->state assignments. While at it, get rid of the erase_info->state field, all MTD_ERASE_XXX definitions and the mtd_erase_callback() function.
