Subject: csky: Cast argument to virt_to_pfn() to (void *)
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ee12fe28ae0e768af776c8e0247e83e59e5c4525;p=linux.git

csky: Cast argument to virt_to_pfn() to (void *)

The virt_to_pfn() function takes a (void *) as argument, fix
this up to avoid exploiting the unintended polymorphism of
virt_to_pfn.
