If anyone has any objections, please let me know. ------------------ From: Javier Martinez Canillas [ Upstream commit a93151a72061e944a4915458b1b1d6d505c03bbf ] If the driver is built as a module, autoload won't work because the module alias information is not filled. So user-space can't match the registered device with the corresponding module. Export the module alias information using the MODULE_DEVICE_TABLE() macro.
