Subject: [PATCH 14/29] usb: fotg210: fix OTG-only build
|
||
|
|
|
||
|
|
The fotg210 module combines the HCD and OTG drivers, which then
|
||
|
|
fails to build when only the USB gadget support is enabled
|
||
|
|
in the kernel but host support is not:
|
||
|
|
|
||
|
|
aarch64-linux-ld: drivers/usb/fotg210/fotg210-core.o: in function `fotg210_init':
|
||
|
|
fotg210-core.c:(.init.text+0xc): undefined reference to `usb_disabled'
|
||
|
|
|
||
|
|
Move the check for usb_disabled() after the check for the HCD module,
|
||
|
|
and let the OTG driver still be probed in this configuration.
|
||
|
|
|
||
|
|
A nicer approach might be to have the common portion built as a
|
||
|
|
library module, with the two platform other files registering
|
||
|
|
their own platform_driver instances separately.
|
||
|
