From d787289589202cd449cabed3d7fde84e18fb6dd6 Mon Sep 17 00:00:00 2001 From: Billy Tsai Date: Tue, 8 Oct 2024 16:14:47 +0800 Subject: [PATCH] gpio: aspeed: Remove the name for bank array The bank array name is only used to determine if the GPIO offset is valid, and this condition can be replaced by checking if the offset exceeds the ngpio property.
