Subject: [PATCH] drm/ttm: Print the memory decryption status just once
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Stop printing the TT memory decryption status info each time tt is created
and instead print it just once.
Reduces the spam in the system logs when running guests with SEV enabled.
