[PATCH v3 0/8] comedi: ni_usb6501: add counter support

[Luca Ellero]

This series of patches add counter support for NI USB-6501. I tested it on my
device and it works fine.

Changes for v2:
- rewrite patch 3/9 changelog: replace "fix" with "cleanup"
- avoid sparse warnings
- add SDF_LSAMPL flag to counter subdevice

Changes for v3:
- remove useless checks
- remove empty lines
- ni6501_auto_attach(): replace spaces with tabs for proper alignment
- squash last 5 patches into a single patch (add counter subdevice) to avoid 
  compilation warnings "function defined but not used"
- rename "counter" local vars to "val" to avoid ambiguity with counter number
- let ni6501_cnt_insn_config() return the insn->n value if it succeeds
- let ni6501_cnt_insn_read read insn->n values
- let ni6501_cnt_insn_write be able to handle an array of values
