The following pateches fix the errors and warnings in 
dgnc_neo.c and dgnc_tty.c to meet kernel coding style.

ERROR: else should follow close brace '}'
ERROR: that open brace { should be on the previous line
WARNING: line over 80 characters
WARNING: braces {} are not necessary for single statement blocks

Fix indenting of if-else statement in dgnc_neo.c and dgnc_tty.c
so that following else-if or else statement meets coding style.

Fix indenting of if statement in dgnc_neo.c so that an open brace
follows if-condition part to meet kernel coding style.

Fix line over 80 characters of if-condition part and also
indent the lines to tell the difference between the condition and
body of the if statement.

Then I think we can keep the readability and meet coding style
with this change.

This isn't the right way.  Write it like this:

	if ((ch->ch_digi.digi_flags & CTSPACE) ||
	    (ch->ch_digi.digi_flags & RTSPACE) ||
	    (ch->ch_c_cflag & CRTSCTS) ||
	    !(ch->ch_digi.digi_flags & DIGI_FORCEDCD) ||
	    !(ch->ch_c_cflag & CLOCAL)) {
		ier |= UART_IER_MSI;
	else
		ier &= ~UART_IER_MSI;

1) The "||" operation goes at the end of the line.
2) The conditions are all in a line.  The indenting is

[tab][space][space][space][space](ch->ch_digi.digi_f...

Also just fold this patch and [patch 2/4] together into one patch.  We
don't need two patches to fix one if statement.

The one thing per patch rule is a bit tricky.  It means that you have to
say which one thing you are fixing.  Don't say "I am fixing three
things."  Say "I am fixing one if statement".

dan carpenter

Sure, I'll modify this.

So in this case, do you think I could fold all four patches into one?
As I just worked on the 'same' if statements and divided them into
four patches, this could be the case. (but I'm not sure yet...)

Also, should I put v[number] for the modified patches?
Say [PATCH v2] staging: ...

Thank you,
Masaru

No.  That would be more than one thing per patch.  It looks like this:

[patch 1/3] staging: dgnc: dgnc_neo: put else statements on the right line
[patch 2/3] staging: dgnc: dgnc_neo: clean up ugly one very ugly condition
[patch 3/3] staging: dgnc: dgnc_neo: remove extra curly braces

Each patch does one thing.  Cleaning up the whole file is too big so it
doesn't count as doing one thing only.

Yes.

Remove unnecessary braces of if-else statements in dgnc_neo.c and
dgnc_tty.c to meet kernel coding style.
