[PATCH 1/2] wcn36xx: Correct Kconfig dependency

[PATCH 1/2] wcn36xx: Correct Kconfig dependency

[Bjorn Andersson]

In the case SMD or WCNSS_CTRL are compiled as modules, wcn36xx must be
compiled as module as well, so we need to mention this dependency.
But we still want allow the driver to be compiled in case either of
those are =n, for compile testing reasons.

[PATCH 2/2] soc: qcom: smem_state: Fix include for ERR_PTR()

[Bjorn Andersson]

The correct include file for getting errno constants and ERR_PTR() is
linux/err.h, rather than linux/errno.h, so fix the include.

Fixes: e8b123e60084 ("soc: qcom: smem_state: Add stubs for disabled smem_state")

Andy, I don't see anything else going into v4.10 for smem_state.h. So if you
are okay I would like Kalle to pick this patch through his tree and be able to
merge my wcn36xx patches for v4.10.

I thought we wanted to move towards being able to compile the WiFi and Bluetooth support without requiring QCOM_SMD.

That's right.

The problem I spotted was that without the dependency on QCOM_SMD we're
allowed to compile these modules as builtin, but as
IS_ENABLED(CONFIG_QCOM_SMD) is true we don't get the stubs and as such
the kernel doesn't link.

So we must enforce these modules to be compiled as modules if either
QCOM_SMD or QCOM_WCNSS_CTRL are compiled as modules, and we do that with
the first part of the depends lines.


The second part of the depends lines states that the alternative
dependency is that the modules are not enabled at all, in which case we
will fall back to using the function stubs.

So this is unfortunately how we have to describe it in Kconfig to work
with the function stubs, sorry for not getting this right in the first
place.

Bjorn
