return 0;

It seems was more appropriate that initialize ret then return ret.
Do you think so ?

What do you mean and how does it help here?

I'm sorry, I was wrong before and the ret varible seems not to be
initialized and it always record the return value for
loongson_spi_init_master.

It seems was appropriate that use "return ret" and I don't got your
point that in probe for use "return 0"

In the above excerpt you will return anything except 0 with return
dev_err_probe(); line. Why do you still need to return ret; at the end
of the function?


I'm sorry, I misread it and you are right and I will "return 0".

Thanks,
Yinbo.
