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.
