comedi: Fix some signed shift left operations
commit ab705c8c35e18652abc6239c07cf3441f03e2cda upstream.
Correct some left shifts of the signed integer constant 1 by some
unsigned number less than 32. Change the constant to 1U to avoid
shifting a 1 into the sign bit.
The corrected functions are comedi_dio_insn_config(),
comedi_dio_update_state(), and __comedi_device_postconfig().
Fixes: e523c6c86232 ("staging: comedi: drivers: introduce comedi_dio_insn_config()")
Fixes: 05e60b13a36b ("staging: comedi: drivers: introduce comedi_dio_update_state()")
