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".
