From 7841d06e4398cff7d744539d1e6ea4026ceab2e5 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 17 Oct 2015 00:03:38 +0200 Subject: [PATCH] Bluetooth: bpa10x: fix BT_HCIUART dependency The change to bpa10x to use the h4_recv_buf helper added a dependency on BT_HCIUART. This was incorrectly added to Kconfig by adding a 'select' statement, which now in turn causes build failures when CONFIG_TTY is not set: warning: (BT_HCIBPA10X) selects BT_HCIUART which has unmet direct dependencies (NET && BT && TTY) vers/built-in.o: In function `hci_uart_tty_receive': fpga-mgr.c:(.text+0x282824): undefined reference to `tty_unthrottle' drivers/built-in.o: In function `hci_uart_tty_ioctl': fpga-mgr.c:(.text+0x282aa0): undefined reference to `n_tty_ioctl_helper' drivers/built-in.o: In function `hci_uart_flush': This replaces the 'select BT_HCIUART' dependency with 'depends on', which does not have this kind of problem. Alternatively, one could add 'depends on TTY', but avoiding 'select' on user-visible options is generally the preferred choice as that does not introduce the potential for dependency loops or incomplete dependency chains.
