There is no call to i2c_get_clientdata() or dev_get_drvdata().
Drop the unnecessary call to i2c_set_clientdata().
Other relevant changes:
  Simplify error return

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 'goto l; ... l: return e;' with 'return e;'
- Replace 'if (e) return e; return 0;' with 'return e;'
- Drop i2c_set_clientdata()
