READ/WRITE definitions in drivers/spi/spi-omap-100k.c

[Tejun Heo]

Hey, guys.

I was modifying includes in a core header file and got duplicate macro
definition warnings on READ / WRITE in drivers/spi/spi-omap-100k.c.
Apparently that driver defines READ / WRITE as macros and assigns the
opposite values to them from the usual READ / WRITE constants defined
in include/linux/fs.h.

I just skimmed through it and there doesn't seem to be any user of the
macros.  Can we *please* remove these?  Please note that READ / WRITE
defined in include/linux/fs.h is something which is widely used
throughout the kernel and there are multiple interfaces which take
those constants.  Re-defining them in the other way around in a driver
file can lead to subtle issues and just is a bad idea.  In general,
refraining from using generic symbols without any qualitification in
low level drivers would be nice.

Thanks.
