Subject: [PATCH linux-next] tee/optee/shm_pool: fix application of sizeof to pointer

From: jing yangyang <jing.yangyang@....com.cn>

sizeof when applied to a pointer typed expression gives the size of
the pointer.

./drivers/tee/optee/shm_pool.c:38:28-34: ERROR application of sizeof to pointer

This issue was detected with the help of Coccinelle.
