memory: emif: Drop usage of platform_driver_probe()
There are considerations to drop platform_driver_probe() as a concept that isn't relevant any more today. It comes with an added complexity that makes many users hold it wrong. (E.g. this driver should have better used __init instead of __init_or_module to mark functions only relevant to .probe() and mark the driver struct with __refdata.) This fixes a W=1 build warning: WARNING: modpost: drivers/memory/emif: section mismatch in reference: emif_driver+0x4 (section: .data) -> emif_remove (section: .exit.text) Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Link: https://lore.kernel.org/r/20240123170846.1362597-2-u.kleine-koenig@pengutronix.de Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
