From 1cfce74fe5a2301ee9b384d9395ba95db930c9d6 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 24 Aug 2016 09:46:32 -0700 Subject: [PATCH] nand: Fix set_dev checks for no device If we do nand device 0 command in u-boot on a device that has NAND support enabled but no NAND chip, we can get data abort at least on omaps. Fix the issue by replacing the check with nand_info[dev] as suggested by Scott Wood. The check for name existed before because before the array-to-pointer conversion there was no way to directly test nand_info[dev] for emptiness.
