Subject: [PATCH 13/15] NTB: remove redundant setting of DB valid mask
Date:   Wed,  5 Feb 2020 21:24:30 +0530

Precedence: bulk

db_valid_mask is set at two places, once within
amd_init_ntb(), and again within amd_init_dev().
Since amd_init_ntb() is actually called from
amd_init_dev(), setting db_valid_mask from
former does not really make sense. So remove it.
