Putting a comment after a single line 'if' and before the statement is
not the norm and can be confusing. Please don't do it.

Also, quite a few of the comments you're moving around here look to be
unecessary, and can probably be deleted.

The guideline is that multi-line indents should get {} braces for
readability even though they aren't needed for syntax.

I took the original comments that were there, and just formatted them to be in order with the coding style, I didn't add or remove anything. This is my first patch so I didn't want to mess too much with what was there before, even if the comments sometimes seemed superfluous to me.

No problem, everyone's first patch is rejected. Just fix it up in line
with the review comments and resend.

That is Linus's tree, not "linux-next" which we all develop against.

Yes please, or maybe put the comment on the return line like:

if (pdx->sCurrentState == U14ERR_TIME)
return; /* Do nothing if hardware in trouble */

or above the test like:

/* Do nothing if hardware in trouble */
if (pdx->sCurrentState == U14ERR_TIME)
return;
