Subject: tty: serial: 8250: Add generic port init macro
X-Git-Tag: next-20160210~21^2~13
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b3bd666807d98d8ea53e578307979f6424175612;p=karo-tx-linux.git

tty: serial: 8250: Add generic port init macro

This patch removes redundant 8250 port initialization macros and
replaces them by a single generic base-macro, which is specialized
as needed.
