Clean up a handful of checkpatch warnings:
 - static const char * array should probably be static const char * const
 - function arguments should have identifier names
 - else should follow close brace '}'
 - suspect code indent for conditional statements
 - unnecessary parentheses in an if condition
 - avoid multiple line dereference
 - prefer using '"%s...", __func__' to using 'ab8500_chargalg_wd_work'
 - prefer 'long' over 'long int' as the int is unnecessary

The subject says cppcheck but it's actually checkpatch.

This printk should just be deleted.  Use ftrace instea.
