Subject: [PATCH 13/15] NTB: remove redundant setting of DB valid mask
Date: Wed, 5 Feb 2020 21:24:30 +0530 [thread overview]
Message-ID: <77ab9d5b86cbf404cd254d50d26e276472014293.1580914232.git.arindam.nath@amd.com> (raw)
In-Reply-To: <cover.1580914232.git.arindam.nath@amd.com>
In-Reply-To: <cover.1580914232.git.arindam.nath@amd.com>
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.
