If anyone has any objections, please let me know. ------------------ From: Haoxiang Li commit 9cb2d5291dbfe7bed565ead3337047dee9ed1064 upstream. efct_dispatch_fcp_cmd() allocates an efct_io before dispatching an unsolicited FCP command. If the command has an unsupported additional CDB, the function returns -EIO before handing the IO to the SCSI layer. Free the allocated IO before returning from this error path.
