Remove the "depends on OF" in Kconfig of PCI controllers. These drivers depends on CONFIG_OF because they use interface in of.h file, e.g. "of_match_ptr()". But these interface are defined as stub if CONFIG_OF is not set. Thus we can compile them without CONFIG_OF, instead just with COMPILE_TEST. Signed-off-by: Fan Fei <ffclaire1224@xxxxxxxxx> --- Hi, Bjorn, I just did as what you suggested, remove the "depends on OF" in Konfig, and compile it. It seems to work well. On the thread https://lore.kernel.org/all/20201005215817.GA3063223@bjorn-Precision-5520/ mentioned by the task excel, there are some replacement of "of_match_ptr()", but this function seems to be defined even CONFIG_OF is not set. Is it correct to reply in this thread or shall I send it to mail list directly?
