category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I60QFD

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=606fe84a41851ab8307bb6096189dc8f4c8ba16b

--------------------------------

Moves the access_ok() check for valid memory range from user space from
the function tee_shm_register() to tee_ioctl_shm_register(). With this
we error out early before anything is done that must be undone on error.

Fixes: 578c349570d2 ("tee: add overflow check in register_shm_helper()")
