Subject: [PATCH] kernel build: issue whith "make tar-pkg" with INSTALL_FW_PATH

Hello,

"make tar-pkg" with set INSTALL_FW_PATH does not work like expected.

Initial situation:
------------------
building a kernel package with
| make tar-pkg INSTALL_FW_PATH=/somewhere


Expected result:
----------------
* tar-archive including the firmware in folder /somehere


Result:
-------
* tar-archive without firmware
* firmware on hd in folder /somewhere


Reason:
-------
Makefile:
| # Firmware install
| INSTALL_FW_PATH=$(INSTALL_MOD_PATH)/lib/firmware
| export INSTALL FW PATH
...
| firmware_install: FORCE
|      @mkdir -p $(objtree)/firmware
|      $(Q)$(MAKE) -f $(srctree)/scripts/Makefile.fwinst obj=firmware
__fw_install

Here INSTALL_MOD_PATH is not considered but is needed for packageing.


Potential fix:
--------------
