Subject: [PATCH 05/33] Input: imx_keypad - Drop unnecessary error messages and other changes

Error messages after memory allocation failures are unnecessary and
can be dropped.

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

- Drop unnecessary braces around conditional return statements
- Drop error message after devm_kzalloc() failure
