Some gpio pin at aspeed soc is input only and the prefix name of these
pin is "GPI" only. This patch fine-tune the condition of GPIO check from
"GPIO" to "GPI".

I'd like it if we were a bit more specific in the commit message, and even
better if we update the comment in the code. A quick look at the code suggests
this issue affects GPIO banks D and E in the AST2400 and AST2500, and banks T
and U in the AST2600.
Functionally I think the patch is fine.
Cheers,
Andrew

Some gpio pin at aspeed soc is input only and the prefix name of these
pin is "GPI" only.
This patch fine-tune the condition of GPIO check from "GPIO" to "GPI"
and it will fix the usage error of banks D and E in the AST2400/AST2500
and banks T and U in the AST2600.
Fixes: 4d3d0e4272d8 ("pinctrl: Add core support for Aspeed SoCs")

Thanks Billy. Generally the Fixes: tag should be part of the trailer block,
hopefully Linus is happy to remove the newline for us!
