From 9cfa3a7bd4755dfc5ef03bbf238a1e3283cbfff4 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Sat, 19 Oct 2013 18:19:25 -0300 Subject: [PATCH] mtd: nand: pxa3xx: Fix registered MTD name In a recent commit: commit dabcc14690b9a070eaaf0b0ea0b42c89542c05af Author: Ezequiel Garcia Date: Mon Aug 12 14:14:53 2013 -0300 mtd: nand: pxa3xx: Remove hardcoded mtd name There's no advantage in using a hardcoded name for the mtd device. Instead use the provided by the platform_device. The MTD name was changed to use the one provided by the platform_device. However, this can be problematic as some users want to set partitions using the kernel parameter 'mtdparts', where the name is needed. Therefore, to avoid regressions in users relying in 'mtdparts' we revert the change and use the previous one 'pxa3xx_nand-0'. While at it, let's put a big comment and prevent this change from happening ever again.
