'type' is an enum, thus cast of pointer on 64-bit compile test with
clang and W=1 causes:

  mxs-lradc.c:140:15: error: cast to smaller integer type 'enum mxs_lradc_id' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]

Year ago this was solved, although LKML discussion suggested warning is
not suitable for kernel.  Nothing changed in this regard for a year, so
assume the warning will stay and we want to have warnings-free builds.
