The "url" link shows all patches of this series in the right order though. All these functions are declared in the linux/input/ts-virtobj.h header and also inline-defined there if ts-virtobj is not selected. If it is selected (either y or M), the functions are exported from driver/input/touchscreen/ts-virtobj.c. According to the error report, ts-virtobj was selected as a module. I could build the kernel with the three possible configurations (ts-virtobj y/n/M) for x86_64 as well as for arm64 with no errors or warnings repeatedly, so I am a bit confused now. I am probably missing something, but I do not know what. I wonder if the new file where the functions are defined (ts-virtobj.c) could not be found by some reason or if the test build does not like the way I handled the function declaration/definition. Any hint or advice would be more than welcome.
