If registering "reg_shm_out" fails, then it is an error pointer and the
error handling will call tee_shm_free(reg_shm_out) which leads to an
error pointer dereference and an Oops.

I've re-arranged it so we only free things that have been allocated
successfully.

I don't have this file (trusted_tee.c) in my tree and there's no lore
link here to previous what threads this depends on.  Based on the
context I can't verify that reg_shm_in will always be initialized
before you get to the free_shm_in label.

Thanks for fixing the error path. Although an alternative simple fix
could be [1] but I liked your approach to get rid of redundant "if"
checks. FWIW:
