And the driver is being built into the kernel with obj-(CONFIG_MY_DRIVER) += my-driver.o, so it's not even a loadable module. I thought fixdep is about finding module dependency, and it isn't needed for built-in drivers. Please correct me if I'm wrong. I want to understand if the .d file had never been generated or had been generated but deleted by the time fixdep tries to open it.
