[Buildroot] kernel module dir following move to git

[Buildroot] kernel module dir following move to git

[Will Wagner]

Hello All,

Following the move to git I am seeing the kernel modules being built to a different 
directory. The code expects modules to be built in 
$(TARGET_DIR)/lib/modules/$(LINUX26_VERSION_PROBED)

LINUX26_VERSION_PROBED is set with
LINUX26_VERSION_PROBED = `$(MAKE) $(LINUX26_MAKE_FLAGS) -C $(LINUX26_DIR) -s kernelrelease`

Since the move to git the kernel has changed what it reports with kernelrelease to 
$(VERSION)-g7664a62a-dirty. Presumably the kernel is spotting that buildroot came from a 
git repository and is appending info about the checkout?

Any suggestion on how to prevent this happening?

Will

Think I have worked this out now. It is because I have CONFIG_LOCALVERSION_AUTO=y set in 
my kernel config file. Still seems odd that it is finding buildroot git rather than a 
kernel git but think I can fix it now.

Well, it's because the kernel's scripts/setlocalversion checks if your
kernel is in a git repo (which it technically is if you build in the
tree and have buildroot from git).

Another workaround is to simply build out of tree (make O=<somewhere>)
