I am fixing the bug entry , https://bugzilla.kernel.org/show_bug.cgi?id=60461. This entry states that we are not checking the skb allocated in fw_download_code for NULL and after checking it ,I fixed it to check for the NULL value before returning false and exiting fw_download_code cleanly. In additon I removed the variable, rt_status as it's easier to read this function's return value with just true or false and rt status is a unneeded variable for the bool return of this function.
