[PATCH] scsi: aic7xxx: fix some problem of return value

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



aic7770_probe() should return negative error code rather than positive.
However, aic7770_config() only return positive error code,
ahc_linux_register_host() return both positive and negative error
code. Make aic7770_probe() return negative if error happened and let
ahc_linux_register_host() only return positive error code to fix this
problem.

ahc_linux_pci_dev_probe() should return the value of
ahc_linux_register_host() rather than zero.
