Subject: [PATCH linux-next] tee/optee/shm_pool: fix application of sizeof to pointer
Date: Thu, 19 Aug 2021 20:21:27 -0700 [thread overview]
Message-ID: <c66fd6f831571b53b741350513e36405bba6c666.1629211976.git.jing.yangyang@zte.com.cn> (raw)
From: jing yangyang <jing.yangyang@zte.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.
