Subject: [PATCH 06/29] usb: fotg210: Fix Kconfig for USB host modules
|
||
|
|
|
||
|
|
The kernel robot reports a link failure when activating the
|
||
|
|
FOTG210 host subdriver with =y on a system where the USB host
|
||
|
|
core is a module (CONFIG_USB=m).
|
||
|
|
|
||
|
|
This is a bit of special case, so mimic the Kconfig incantations
|
||
|
|
from DWC3: let the subdrivers for host or peripheral depend
|
||
|
|
on the host or gadget support being =y or the same as the
|
||
|
|
FOTG210 core itself.
|
||
|
|
|
||
|
|
This should ensure that either:
|
||
|
|
|
||
|
|
- The host (CONFIG_USB) or gadget (CONFIG_GADGET) is compiled
|
||
|
|
in and then the FOTG210 can be either module or compiled
|
||
|
|
in.
|
||
|
|
|
||
|
|
- The host or gadget is modular, and then the FOTG210 module
|
||
|
|
must be a module too, or we cannot resolve the symbols
|
||
|
|
at link time.
