PCI: add pci_try_set_mwi
As suggested by Andrew, add pci_try_set_mwi(), which does not require return-value checking. - add pci_try_set_mwi() without __must_check - make it return 0 on success, errno if the "try" failed or error - review callers Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Cc: Alan Cox <alan@lxorguk.ukuu.org.uk> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
