serial/8250: Increase number of serial ports detected to 32

[Yegor Yefremov]

Binary package hint: linux-generic

CONFIG_SERIAL_8250_RUNTIME_UARTS should be
increased to at least 32 in order to support multi port serial cards out of the
box. This will cover at least the situation, where two 8 port cards are used
simultaneously and there is still some room for internal ports or the other
card.

This bug report was created after initial discussion on the linux-serial
mailings list: http://www.spinics.net/lists/linux-serial/msg03020.html

The same bug was already accepted by openSUSE: https://bugzilla.novell.com/show_bug.cgi?id=652954

Here is a patch for Ubuntu 11.04. Applied against git://kernel.ubuntu.com/ubuntu/ubuntu-natty.git. Please review.

Thanks Yegor.

I've reassigned this to the linux kernel package and added it as a tracking item to the config-review blueprint for Natty:
