Subject: fix WARN() for PPC
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f6f286f33e843862c559bfea9281318c4cdec6b0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

fix WARN() for PPC

powerpc doesn't use the generic WARN_ON infrastructure.  The newly
introduced WARN() as a result didn't print the message, this patch adds
the printk for this specific case.
