Subject: [PATCH v4] bus: ti-sysc: Change return types of functions
Date:   Thu, 15 Aug 2019 11:16:47 +0530

Change return type of functions sysc_check_one_child() and
sysc_check_children() from int to void as neither ever returns an error.
Modify call sites of both functions accordingly.

Changes in v4:
- Merge into a single patch the two patches for sysc_check_one_child()
  and sysc_check_children().
Changes in v3:
- Add patch for sysc_check_children().
- Remove return statement in sysc_check_one_child().
- Remove braces at call site.
Changes in v2:
- Remove error variable entirely.
- Change return type of sysc_check_one_child().
