Subject: [PATCH 3/9] NTB: Fix typo in setting one translation register
From: Roland Dreier <roland@...estorage.com>
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
(SNB_MBAR01_DSD_ADDR vs. SNB_MBAR01_USD_ADDR).
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.
