From 2f9eca8cdcc83e9df5e6f8fb0731dac4bc27001a Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 6 Jul 2012 08:10:26 +0200 Subject: [PATCH] mtd: m25p80: Fix the Spansion chip detection Due to the implementation of the following loop at the end of jedec_probe(): 776 for (tmp = 0; tmp < ARRAY_SIZE(m25p_ids) - 1; tmp++) { 777 info = (void *)m25p_ids[tmp].driver_data; 778 if (info->jedec_id == jedec) { 779 if (info->ext_id != 0 && info->ext_id != ext_jedec) 780 continue; 781 return &m25p_ids[tmp]; 782 } 783 } In particular line 779 in the above numbering, the chips with ext_id != 0 must be ordered first in the list of chips (m25p_ids[]).
