# This function must be here BEFORE the require of linux-dtb.inc below.
# There is a "bug" in the base kernel.bbclass that after it's do_deploy
# step it does not return back to the ${S} directory but stays in the
# DEPLOY_DIR. However, the do_deploy_append defined in linux-dtb.inc
# assumes that it is being run in the ${S} directory. A patch is
# being submitted to fix this issue by either changing the do_deploy
# in the kernel.bbclass to do "cd -" as the last step or to add
# "cd ${S}" as the first line of do_deploy in linux-dtb.inc and this
# function can be removed once that change is available.
# If the function is not placed BEFORE the require then the change
# directory is not appended before the linux-dtb.inc changes.
