I shouldn't have just blindly followed what Hector and Joey had to do for another subsystem to make reference counting work there. I just checked again and it's neither required here not in struct nvmem_config because module_platform_driver -> platform_driver_register -> __platform_driver_register will set it in struct platform_driver and the nvmem core will take it from there and set it inside nvmem_config. thanks, Sven ^ permalink raw reply [flat|nested] 5+ messages in thread
