From b1c6e6db5bb7acad82e1c64914c6a9404dae3ee1 Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 2 Nov 2009 18:12:33 +0000 Subject: mtd: nand: add option to quieten off the no device found messgae Add NAND_SCAN_SILENT_NODEV to chip->options to the user-worrying messages 'No NAND device found!!!'. This message often worries users (was three exclamation marks really necessary?) and especially in systems such as the Simtec Osiris where there may be optional NAND devices which are not known until probe time. Revised version of the original NAND_PROBE_SPECULATIVE patch after comments by Artem Bityutskiy about adding a whole new call.
