The newly added nfcmrvl_spi driver uses the spi_nci infrastructure, but does not have a Kconfig dependency on that, so we can get a link-time error: drivers/built-in.o: In function `nfcmrvl_spi_nci_send': (.text+0x1428dc): undefined reference to `nci_spi_send' drivers/built-in.o: In function `nfcmrvl_spi_probe': (.text+0x142a24): undefined reference to `nci_spi_allocate_spi' drivers/built-in.o: In function `nfcmrvl_spi_int_irq_thread_fn': (.text+0x142abc): undefined reference to `nci_spi_read' This clarifies the dependency.
