* [PATCH] mfd: sec: initialize driver via module_platform_driver @ 2020-09-21 20:34 ` Krzysztof Kozlowski 2020-09-22 8:04 ` Marek Szyprowski 0 siblings, 1 reply; 2+ messages in thread From: Krzysztof Kozlowski @ 2020-09-21 20:34 UTC (permalink / raw) To: Sangbeom Kim, Krzysztof Kozlowski, Bartlomiej Zolnierkiewicz, Lee Jones, linux-kernel, linux-samsung-soc The driver was using subsys_initcall() because in old times deferred probe was not supported everywhere and specific ordering was needed. Since probe deferral works fine and specific ordering is discouraged (hides dependencies between drivers and couples their boot order), the driver can be converted to regular module_platform_driver.
