Subject: [PATCH] openrisc: include: asm: define empty SERIAL_PORT_DFNS in serial.h
Date: Thu, 31 Oct 2013 09:54:04 +0800	[thread overview]
Message-ID: <5271B83C.50807@asianux.com> (raw)

For some architectures (e.g. openrisc, arc), BASE_BAUD isn't constant
And SERIAL_PORT_DFNS always use BASE_BAUND, and also all drivers use
SERIAL_PORT_DFNS to initialize static variables, statically.

So need define SERIAL_PORT_DFNS as empty to tell drivers they don't
support SERIAL_PORT_DFNS (mostly like frv and parisc did).
