Ia0957b47187c3dcadd46154b17022c4213781112 proposes to have bashate find instances of setting a local value. The issue is that "local" always returns 0, thus hiding any failure in the commands running to set the variable. This is an automated replacement of such instances Depends-On: I676c805e8f0401f75cc5367eee83b3d880cdef81 Change-Id: I9c8912a8fd596535589b207d7fc553b9d951d3fe
