source code size, improve readability, and reduce the likelyhood of bugs.
Other improvements as listed below.

following semantic patches. The semantic patches and the scripts

- Drop assignments to otherwise unused variables
- Drop empty remove function
- Use local variable 'struct device *dev' consistently
