It's caused by the following line in pcmcia/cardbus.c:read_cb_mem():
memcpy_fromio(ptr, s->cb_cis_virt + addr, len);
s->cb_cis_virt is void __iomem * per include/pcmcia/ss.h while
memcpy() takes const void * for argument 2.
I don't have a recent tree, but adding a cast to the call should
silence the warning:
memcpy_fromio(ptr, (const void *)s->cb_cis_virt + addr, len);
