[U-Boot] [PATCH] power: twl6030: fix code refactoring

[Nicolae Rosia]

From: Nicolae Rosia <nicolae.rosia@gmail.com>

Commit a85362fb3e1fc7833723accddbbae431091d06b8 refactored the code
but the register read ended up in the wrong if branch.
Currently, the else branch checks a variable which is always 0.

Good catch! Sorry for including that regression in the first place, I should
have checked the patch more thoroughly.

See comment below.

The indentation before &value is inconsistent with what is done in the rest of
the file. I think you should either just move the line as it was or only use one
extra tab indent for the new line. Since this file breaks the 80 chars limit in
a few places, I would tend to prefer the former.

checkpatch.pl was complaining, that's why I formatted it.
@Tom Rini, can you apply it either way?

Best regards,
Nicolae

I'll take this and do you want to do a follow up to make the file
checkpatch clean?  Thanks!

Then I think you should fix the rest of the file accordingly.

It doesn't make sense to introduce a variation in the coding style, as it
creates inconsistency. IMO this is worse than having only subsequent changes
conform to the global U-Boot coding style.

Either way works for me, I can do the follow up to make the file
checkpatch clean.
