Sorry, but this isn't how it is done... > +config PTP_DFL_TOD > + tristate "FPGA DFL ToD Driver" > + depends on FPGA_DFL > + depends on PTP_1588_CLOCK Try these commands: git grep "depends on PTP_1588_CLOCK_OPTIONAL" git grep "depends on PTP_1588_CLOCK_OPTIONAL" | grep -v OPTIONAL Driver must depend on PTP_1588_CLOCK_OPTIONAL and then handle the NULL case correctly.
