Subject: of/fdt: don't ignore errors from of_setup_earlycon
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=b204731689059f0e27b676e86b089d59bd1a4805;p=uclinux-h8%2Flinux.git

of/fdt: don't ignore errors from of_setup_earlycon

If of_setup_earlycon we should keep on iterating earlycon options
instead of breaking out of the loop.
