From a7f5ba40c74e67b2c8c6e15425157ab6775621d7 Mon Sep 17 00:00:00 2001 From: Boris BREZILLON Date: Thu, 1 Oct 2015 16:58:27 +0200 Subject: [PATCH] mtd: nand: remove unused ->init_size() hook The ->init_size() hook was introduced to let NAND controller drivers support NAND devices that could not be described in the nand_ids table. Since then, the core has added support for extended-id parsing and full-id description, thus allowing to describe pretty much all existing NANDs. Moreover, this hook is not used by any mainline driver, and should not be used by new drivers, because detecting the NAND chip is not something controller specific.
