Subject: [PATCH 1/3] ppc64-diag: Move trim_trail_space() function to
 common/utils.c

Upstream: merged, expected in 2.7.10
Git-commit: c507319d1b5f0286d67e08a3598949ca4144f475

Currently, trim_trail_space() function is used in diags/diag_nvme.c file
to be able to trim trailing white spaces from a given location code. Allow
code reusability by moving the trim_trail_space() function from
diags/diag_nvme.c to common/utils.c.
