Using pr_info in a header exposes us to potential trouble from
subsystems that define pr_fmt.  This change fixes:

  In file included from include/linux/scatterlist.h:10,
                   from include/scsi/scsi.h:12,
                   from drivers/infiniband/ulp/srp/ib_srp.c:46:
  arch/tile/include/asm/io.h: In function ‘ioport_map’:
  arch/tile/include/asm/io.h:296: error: expected ‘)’ before ‘PFX’

It'd be nicer to add an appropriate KERN_<LEVEL> here.

My preference would be to change ib_srp.c (and ib_srpt) like:

Makes sense to me, and it does fix the compile failure.  I've pulled my original change from my tree and instead, for the change above (assuming Joe is implicitly providing a Signed-off-by on this patch):
