ARM: 7941/2: Fix incorrect FDT initrd parameter override
Commit 65939301acdb (arm: set initrd_start/initrd_end for fdt scan) caused the FDT initrd_start and initrd_end to override the phys_initrd_start and phys_initrd_size set by the initrd= kernel parameter. With this patch initrd_start and initrd_end will be overridden if phys_initrd_start and phys_initrd_size are set by the kernel initrd= parameter. Fixes: 65939301acdb (arm: set initrd_start/initrd_end for fdt scan) Signed-off-by: Ben Peddell <klightspeed@killerwolves.net> Acked-by: Jason Cooper <jason@lakedaemon.net> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
