Subject: arcnet: arcdevice.h: Add arcnet_readb and arcnet_writeb
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=9c76aa55110a48c0db1eab4c998a5b94d9f0f852;p=deliverable%2Flinux.git

arcnet: arcdevice.h: Add arcnet_readb and arcnet_writeb

Use the same indirection as the other arcnet_<I/O> macros.
Neither of these new macros add the BUS_ALIGN use for 8 bit devices
on 16 bit busses.
