Subject: omap3: overo: Fix fdtfile test
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=115e71f7da1f6fd96c20793842f5751897d9fdee;p=u-boot.git

omap3: overo: Fix fdtfile test

Commit 12cc54376768461533b55ada1b0b6d4979f40579 'omap3: overo: Select
fdtfile for expansion board' wrongly missed the operator in the fdtfile
test. Update the test to only overwrite an empty fdtfile environment
variable.
