From: Arnd Bergmann Date: Mon, 3 Jul 2023 11:29:13 +0000 (+0200) Subject: cxl: fix CONFIG_FW_LOADER dependency X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9171dfcda4f26dc6ebfd8d50137c5f294c2060ee;p=linux.git cxl: fix CONFIG_FW_LOADER dependency When FW_LOADER is disabled, cxl fails to link: arm-linux-gnueabi-ld: drivers/cxl/core/memdev.o: in function `cxl_memdev_setup_fw_upload': memdev.c:(.text+0x90e): undefined reference to `firmware_upload_register' memdev.c:(.text+0x93c): undefined reference to `firmware_upload_unregister' In order to use the firmware_upload_register() function, both FW_LOADER and FW_UPLOAD have to be enabled, which is a bit confusing. In addition, the dependency is on the wrong symbol, as the caller is part of the cxl_core.ko module, not the cxl_mem.ko module.
