From d8fc1c7c4c9b705ce5f5bba772ad66a0137c685d Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Mon, 25 Apr 2022 09:16:17 -0500 Subject: tee: remove flags TEE_IOCTL_SHM_MAPPED and TEE_IOCTL_SHM_DMA_BUF These look to be leftover from an early edition of this driver. Userspace does not need this information. Checking all users of this that I have access to I have verified no one is using them. They leak internal use flags out to userspace. Even more they are not correct anymore after a45ea4efa358. Lets drop these flags before someone does try to use them for something and they become ABI.
