The commit de516379e85f ("scsi: megaraid_sas: changes to function

function prototype of read_fw_status_reg() to take an instance pointer
instead, but forgot to remove an unused variable.
Certain ttys operations (pty_unix98_ops) lack tiocmget() and tiocmset()

This patch corrects the SPDX License Identifier style
in header files related to Drivers for Intel(R) Trace Hub
controller.
For C header files Documentation/process/license-rules.rst
mandates C-like comments (opposed to C source files where
C++ style should be used)

Braino introduced in "switch the remnants of releasing the mountpoint
away from fs_pin"; the most visible result is leaking struct mount when
mounting btrfs, making it impossible to shut down.
