[PATCH v4 0/3] chrt: Improve argument handling and allow optional priority

This series improves the usability and correctness of the chrt tool:

- Minor cleanups such as indentation fixes and correcting comment.
- Fixes an issue where specifying a policy without a priority would
  misleadingly print current settings
- Makes the priority argument optional for scheduling policies that
  ignore it, simplifying usage for tuning parameters like --sched-runtime

Changes in v4:
- Rectified my mistake of not giving proper space in a comment in v3

Changes in v3: 
- Made --pid consistent throughout (Karel Zak)
- Change get policy to not have policy options (Karel Zak and Benno Schulenberg)

Changes in v2:
- Updated the man page to reflect the optional priority behavior (Karel Zak)
- Renamed variable to 'need_prio' (Karel Zak)

Madadi Vineeth Reddy (3):
  chrt: Make minor cleanups in chrt
  chrt: Only display current settings when no policy is specified
  chrt: Make priority optional for policies that don't use it
