Subject: tee: optee: Pass a pointer to virt_addr_valid()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a3b9ecc805e9131476c719111fe347c7dbc0d1d1;p=linux.git

tee: optee: Pass a pointer to virt_addr_valid()

A pointer into virtual memory is represented by a (void *)
not an u32, so the compiler warns:

drivers/tee/optee/call.c:365:29: warning: passing argument 1
  of 'virt_to_pfn' makes pointer from integer without a
  cast [-Wint-conversion]

Fix this with an explicit cast.
