The thp7312 driver uses the firmware upload API to update the firmware stored in a flash memory connected to the device. The API is gated by the CONFIG_FW_UPLOAD option, and is correctly stubbed in include/linux/firmware.h. As firmware upload is not used in normal operation, the driver expects to compile and link when CONFIG_FW_UPLOAD is disabled. While CONFIG_FW_UPLOAD is a boolean option, whether the firmware upload code is built in the kernel or provided as a module is controlled through the tristate CONFIG_FW_LOADER option that CONFIG_FW_UPLOAD depends on. This results in the following configuration being accepted by Kconfig, compiling properly, but failing to link: CONFIG_FW_LOADER=m CONFIG_FW_UPLOAD=y CONFIG_VIDEO_THP7312=y Fix it by adding a dependency on FW_LOADER.
