Subject: [PATCH 2/2] of: Add check to of_scan_flat_dt() before accessing initial_boot_params
Date: Mon, 21 Nov 2016 17:23:03 +0100 [thread overview]
Message-ID: <2281020.GC1GkRyGht@loki> (raw)
In-Reply-To: <2966402.rBqcQZDeOh@loki>
An empty __dtb_start to __dtb_end section might result in initial_boot_params
being null for arch/mips/ralink. This showed that the boot process hangs
indefinitely in of_scan_flat_dt().
