Subject: [PATCH 1504/5403] drivers: remove get_task_comm() and print task comm
 directly
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Since task->comm is guaranteed to be NUL-terminated, we can print it
directly without the need to copy it into a separate buffer.  This
simplifies the code and avoids unnecessary operations.
