Subject: [PATCH v3 1/2] bus: ti-sysc: sysc_check_one_child(): Change return type to void

Change return type of function sysc_check_one_child() from int to void
as it always returns 0. Remove the now-unnecessary return statement as
well. Accordingly, at its call site, delete the error variable that
previously stored the return value.

Signed-off-by: Nishka Dasgupta <nishkadg.linux@...il.com>
---
Changes in v3:
- 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().
