It's valid to set: COMPILE_TEST=y QCOM_SMD=y WCNSS_CTRL=m BT_QCOMSMD=y which will cause the qcom_wcnss_open_channel issue above to remain. For the wcn36xx driver we cover both with: depends on QCOM_WCNSS_CTRL || QCOM_WCNSS_CTRL=n depends on QCOM_SMD || QCOM_SMD=n The ath-maintainers didn't want COMPILE_TEST due to some unrelated reasons, but I think it's better to express it in two statements, i.e. depends on QCOM_WCNSS_CTRL || (COMPILE_TEST && QCOM_WCNSS_CTRL=n) depends on QCOM_SMD || (COMPILE_TEST && QCOM_SMD=n) Regards, Bjorn > --- > Sent on March 1 2017 originally, still needed for v4.11-rc2 > --- > drivers/bluetooth/Kconfig | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/bluetooth/Kconfig b/drivers/bluetooth/Kconfig > index c2c14a12713b..2ef2b240b31b 100644 > --- a/drivers/bluetooth/Kconfig > +++ b/drivers/bluetooth/Kconfig > @@ -344,7 +344,7 @@ config BT_WILINK > > config BT_QCOMSMD > tristate "Qualcomm SMD based HCI support" > - depends on (QCOM_SMD && QCOM_WCNSS_CTRL) || COMPILE_TEST > + depends on (QCOM_SMD && QCOM_WCNSS_CTRL) || (COMPILE_TEST && QCOM_SMD=n) > select BT_QCA > help > Qualcomm SMD based HCI driver. > -- > 2.9.0 > -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
