  Target Milestone: ---

Hello,

I've successfully build my system up to 2020.02.

But when I started to try to build 2020.02.1 and onwards it always failed with
"depmod: ERROR: Bad version passed" message during TARGET_FINALIZE step.

I managed to find the commit that make my build fail:

8f5a610fe81676092a6960415717de731f43f8bf
linux: Allow modprobe for out-of-tree modules

When LINUX_TARGET_FINALIZE_HOOKS are call the new LINUX_RUN_DEPMOD function
fail in my case.

# Run depmod in a target-finalize hook, to encompass modules installed by
# packages.
define LINUX_RUN_DEPMOD
        $(HOST_DIR)/sbin/depmod -a -b $(TARGET_DIR) $(LINUX_VERSION_PROBED)
endef
LINUX_TARGET_FINALIZE_HOOKS += LINUX_RUN_DEPMOD

Here is my $(LINUX_VERSION_PROBED): 4.19.78-linux4sam-6.2 

I'm using a buildroot external tree for my board, still I've attached my
.config file if it can help

What I don't understand is that if I run manually the depmod command it pass
successfully :/

OK

Any help appreciated!
