From 93d3232d9607669f33a34d3a552b24e1d727413b Mon Sep 17 00:00:00 2001 From: Rostislav Lisovy Date: Tue, 16 Sep 2014 14:38:52 +0200 Subject: [PATCH] cmd_nand: Update (nand_info_t*)nand after arg_off(_size) call The arg_off() and arg_off_size() update the 'current NAND device' variable (dev). This is then used when assigning the (nand_info_t*)nand value. Place the assignment after the arg_off(_size) calls to prevent using incorrect (nand_info_t*) nand value.
