Here is the set of patches, that fixes one of the isssue reported by
Richard Acayan, while doing fix for the reported issue, found various
other issues in the existing code.

This set contains some of those cleanups along with few trivial coding
style patches which looked uncomfortable to read.

Patch 1 should be enough to fix the issue reported.

Tested this is on UNO-Q.
