tg3: fix return value check in tg3_read_vpd()
Besides -ETIMEDOUT and -EINTR, pci_read_vpd may return other error values like -ENODEV or -EINVAL which are ignored due to the buggy check, but the data are not read from VPD anyway and this is checked subsequently with at most 3 needless loop iterations. This does not show up as a runtime bug. CC: Matt Carlson <mcarlson@broadcom.com> CC: Michael Chan <mchan@broadcom.com> Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: David S.
