Bluetooth: hci_uart: fix kconfig dependency
We see the following link error with CONFIG_BT_HCIUART=y, CONFIG_BT_HCIUART_LL=y and CONFIG_SERIAL_DEV_BUS=m: drivers/built-in.o: In function 'll_close': supp.c:(.text+0x55add4): undefined reference to 'serdev_device_close' supp.c:(.text+0x55add4): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol 'serdev_device_close' drivers/built-in.o: In function 'll_open': supp.c:(.text+0x55aed0): undefined reference to 'serdev_device_open' supp.c:(.text+0x55aed0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol 'serdev_device_open' drivers/built-in.o: In function `hci_ti_probe': supp.c:(.text+0x55b00c): undefined reference to 'hci_uart_register_device' supp.c:(.text+0x55b00c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol 'hci_uart_register_device' drivers/built-in.o: In function `ll_setup': supp.c:(.text+0x55b08c): undefined reference to 'serdev_device_set_flow_control' supp.c:(.text+0x55b08c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol 'serdev_device_set_flow_control' supp.c:(.text+0x55b324): undefined reference to 'serdev_device_set_baudrate' supp.c:(.text+0x55b324): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol 'serdev_device_set_baudrate' drivers/built-in.o: In function 'll_init': supp.c:(.init.text+0x1b508): undefined reference to '__serdev_device_driver_register' supp.c:(.init.text+0x1b508): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol '__serdev_device_driver_register' Fix this by dependig BT_HCIUART_LL on the BT_HCIUART_SERDEV symbol. This implies a dependency on BT_HCIUART and hci_ll.c is only compiled in if SERIAl_DEV_BUS is built in or SERIAL_DEV_BUS and BT_HCIUART are modules.
