aic7770_config() returns both negative and positive error code.
it's better to make aic7770_probe() only return negative error codes.
And the previous patch made ahc_linux_register_host() return negative error
codes, which makes sure aic7770_probe() returns negative error codes.

Unrelated to your fix, but 'name' is leaking here.
Also, kasprintf() could be used to avoid buf+sprintf()+kstrdup()
The GFP_ATOMIC in the allocation could certainly also be just a GFP_KERNEL.
