I think the simplest way to fix this is to remove the gate on the definitions in hci_uart.h. Since the constants are macros, there's no runtime cost to doing so, and nothing seems to rely on their absence in the BT_HCIUART_H4=n case. I let randconfig builds run for awhile in drivers/bluetooth/ and didn't hit anything else, so hopefully this was the only fallout.

So maybe, that should be denoted in the Kconfig files? Thanks for looking Paul. Yes, my fix will cause a link error with other randconfigs, which my 'make randconfig drivers/bluetooth/' test loop missed after I made the function prototype always defined, whoops. We do need the dependencies here, as you note. The btmtksdio case syzbot found is the odd one out because it only uses the constants, and doesn't call h4_recv_buf(). Hopefully this gets it all: -----8<----- From: Calvin Owens <calvin@wbinvd.org> Subject: [PATCH v2] Bluetooth: Fix build after header cleanup Some Kconfig dependencies are needed after my recent cleanup, since the core code has its own option. Since btmtksdio does not actually call h4_recv_buf(), move the definitions it uses outside the BT_HCIUART_H4 gate in hci_uart.h to avoid adding a dependency for btmtksdio. The rest I touched (bpa10x, btmtkuart, and btnxpuart) do really call h4_recv_buf(), so the dependency is required, add it for them.

Since btmtksdio does not actually call h4_recv_buf(), move the definitions it uses outside the BT_HCIUART_H4 gate in hci_uart.h to avoid adding a dependency for btmtksdio. The rest I touched (bpa10x, btmtkuart, and btnxpuart) do really call h4_recv_buf(), so the dependency is required, add it for them.
