From f1bc03e7e9bbbb18ad60ad6c6908b16fb7f40545 Mon Sep 17 00:00:00 2001 From: Billy Tsai Date: Tue, 8 Oct 2024 16:14:46 +0800 Subject: [PATCH] gpio: aspeed: Change the macro to support deferred probe Use module_platform_driver() to replace module_platform_driver_probe(). The former utilizes platform_driver_register(), which allows the driver to defer probing when it doesn't acquire the necessary resources due to probe order. In contrast, the latter uses __platform_driver_probe(), which includes the comment "Note that this is incompatible with deferred probing." Since our GPIO driver requires access to the clock resource, the former is more suitable.
