[PATCH 13/33] Input: bfin_rotary - Use 'dev' instead of dereferencing it and other changes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Use local variable 'dev' instead of dereferencing it several times.
Other relevant changes:
  Replace devm_add_action() with devm_add_action_or_reset()

This conversion was done automatically with coccinelle using the
following semantic patches. The semantic patches and the scripts
used to generate this commit log are available at
https://github.com/groeck/coccinelle-patches

- Replace devm_add_action() followed by failure action with
  devm_add_action_or_reset()
- Drop unnecessary braces around conditional return statements
- Use local variable 'struct device *dev' consistently
