Honour the return value of pci_enable_device(), which
seems to be a desirable thing to do:
2.6.20-rc4
gcc (GCC) 4.1.2 20061115 (prerelease) (Debian 4.1.1-21)
CC [M] drivers/message/fusion/mptbase.o
drivers/message/fusion/mptbase.c: In function `mpt_resume':
drivers/message/fusion/mptbase.c:1541: warning: ignoring return value
of `pci_enable_device', declared with attribute warn_unused_result
It also in turn has mptscsih_resume() honour the return value of
mpt_resume()
I'm not sure about the handling of the other potential error cases
in mpt_resume(), of which there appear to be many. But this does
seem to be a good start.
