android - 在linux中注册驱动程序

Question

您能帮我理解 platform_driver_register 与 driver_register 之间的区别吗？

Answer 1

答案非常明显。

platform_driver_register 构建于 driver_register 之上。

int platform_driver_register(struct platform_driver *drv)

{

drv->driver.bus = &platform_bus_type;

if (drv->probe)

 drv->driver.probe = platform_drv_probe;

if (drv->remove)

 drv->driver.remove = platform_drv_remove;

if (drv->shutdown)

 drv->driver.shutdown = platform_drv_shutdown;

return driver_register(&drv->driver);

}
