staging: comedi: ni_tio_internal: simplify ni_tio_counting_mode_registers_present()
Only the e series gpct variant does not have counting mode registers.
Simplfy this function. For aesthetics, return bool instead of int.
This fixes the checkpatch.pl issues:
CHECK: spaces preferred around that '*' (ctx:ExV)
CHECK: Avoid crashing the kernel - try using WARN_ON & recovery code
rather than BUG() or BUG_ON()
