[4/6] PCI: Remove __must_check from definitions

Commit Message

Bjorn Helgaas April 12, 2013, 8:48 p.m. UTC

The __must_check (gcc "warn_unused_result") attribute only makes sense
when compiling the *caller* of the function, so the attribute should
appear on the declaration in the header file, not on the definition.

The declarations of these functions are already annotated with
__must_check.
