You have quoted and a few us in the sentences above, but I'm afraid the end result is not correct (e.g. this patch has nothing to do with platform devices being registered or not). Pleas try to explain why you think this change is necessary with your own words. > This patch set addresses this by making BT_HCIUART_BCM dependent on > SERIAL_DEV_CTRL_TTYPORT which in turn is dependent on SERIAL_DEV_BUS > and ensures that if SERIAL_DEV_BUS is selected is the code is build it. This patch does not touch BT_HCIUART_BCM, so the above paragraph is more suited for a cover letter. Also when resubmitting a patch series, make it self-contained rather than send individual patches in response to their earlier counterparts (which messes up threading). > Signed-off-by: Ian W MORRISON <ianwmorrison@xxxxxxxxx> > --- > drivers/tty/serdev/Kconfig | 4 ++-- > 1 file changed, 2 insertions(+), 2 deletions(-) > > diff --git a/drivers/tty/serdev/Kconfig b/drivers/tty/serdev/Kconfig > index cdc6b820cf93..1144f4db5087 100644 > --- a/drivers/tty/serdev/Kconfig > +++ b/drivers/tty/serdev/Kconfig > @@ -2,7 +2,7 @@ > # Serial bus device driver configuration > # > menuconfig SERIAL_DEV_BUS > - tristate "Serial device bus" > + bool "Serial device bus" So please explain why you think this is needed.
