[PATCH] uio: convert to vm_fault_t

[PATCH] uio: convert to vm_fault_t

[Souptick Joarder]

As part of commit 9b85e95a3080 ("uio: Change return
type to vm_fault_t") in 4.19-rc1, this conversion
was missed. Now converted 'ret' to vm_fault_t type.

Greg, this was missed. Yes, this is not a regression fix,
but can we get this patch in 4.19-rc-X else it might go untraced
and later generate compile error when actual vm_fault_t will be
introduced ?
