[PATCH 24/37] staging: comedi: remove comedi_clear_minor()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



`comedi_clear_minor()` calls either `comedi_clear_board_minor()` or
`comedi_clear_subdevice_minor()` depending on its minor device number
parameter.  The one it calls only depends on where it is called from, so
bypass the calls to `comedi_clear_minor()` and remove it.
