Subject: [PATCH v3 5/6] gpio: aspeed: Change the macro to support deferred probe
Date: Fri, 13 Sep 2024 15:43:24 +0800 [thread overview]
Message-ID: <20240913074325.239390-6-billy_tsai@aspeedtech.com> (raw)
In-Reply-To: <20240913074325.239390-1-billy_tsai@aspeedtech.com>
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.
