[PATCH 3/9] NTB: Fix typo in setting one translation register

From: Jon Mason
Date: Mon Apr 07 2014 - 22:00:16 EST

From: Roland Dreier <roland@xxxxxxxxxxxxxxx>

In the code for Xeon devices in back-to-back mode with xeon_errata_workaround
disabled, the downstream device puts the wrong value in SNB_B2B_XLAT_OFFSETL

This was spotted while reading code, since the typo has no practical effect,
at least for now: the low 32 bits of both constants are actually identical
anyway. However, it's clearer and safer to use the right name.
