From 422485da15e7e9e6f71a5efd1aa2248595cb486d Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Fri, 8 Jul 2016 10:36:39 -0700 Subject: mtd: nand: brcmnand: Change BUG_ON in brcmnand_send_cmd Change the BUG_ON() condition in brcmnand_send_cmd() which checks for the interrupt status "controller ready" bit to a WARN_ON. There is no good reason to kill the system when this condition occur because we could have systems which listed the NAND controller as available (e.g: from Device Tree), but the NAND chip could be malfunctioning and not responding.
