From 1fb78fb6c6ad3751cce18d37e773d07858c1ced9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 19 Apr 2017 19:50:18 +0200 Subject: Bluetooth: try to improve CONFIG_SERIAL_DEV_BUS dependency With CONFIG_SERIAL_DEV_BUS=m, the hci_serdev.o file does not actually get built into hci_uart.o as the Makefile doesn't pick it up, leading to a link error with anything referring to it: ERROR: "hci_uart_register_device" [drivers/bluetooth/hci_nokia.ko] undefined! scripts/Makefile.modpost:91: recipe for target '__modpost' failed Changing this in the Makefile would cause another problem when hci_uart itself is built-in and cannot reference symbols from the serdev module. This tries to address both problems by introducing a new hidden Kconfig symbol that controls both the compilation of hci_serdev.o and whether the Nokia driver can be selected. This seems to address the problem for me, though there might be a better way to do it.
