[PATCH 30/33] Input: raydium_i2c_ts - Simplify error return and other changes

[Guenter Roeck]

Simplify error return if the code returns anyway.
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()
- Replace 'goto l; ... l: return e;' with 'return e;'
- Replace 'if (e) return e; return 0;' with 'return e;'
