Hmm... I double-checked at next-20200312. This function is defined
at linux/property.h header:
include/linux/property.h:const char *fwnode_get_name(const struct fwnode_handle *fwnode);
Its implementation is at drivers/base/property.c, and this is always
built, according with drivers/base/Makefile:
obj-y := component.o core.o bus.o dd.o syscore.o \
driver.o class.o platform.o \
cpu.o firmware.o init.o map.o devres.o \
attribute_container.o transport_class.o \
topology.o container.o property.o cacheinfo.o \
devcon.o swnode.o
The v4l2-fwnode.c properly includes include/linux/property.h.
So, at least up to next-20200312, everything looks fine on my eyes.
The header is probably there, as the error happened at link stage.
Maybe there is some merge conflict caused by merging a patch from
some other tree that might have renamed or removed its implementation
after next-20200312, or changed from obj-y target?
Or maybe this changeset got reverted?
