i2c defines two callbacks (inb/outb). On ia64, since it defines also two macros
with those names, it causes the following errors:
drivers/media/video/usbvision/usbvision-i2c.c:64:39: macro "outb" passed 4 arguments, but takes just 2
drivers/media/video/usbvision/usbvision-i2c.c: In function `try_write_address':
drivers/media/video/usbvision/usbvision-i2c.c:64: warning: assignment makes integer from pointer without a cast
drivers/media/video/usbvision/usbvision-i2c.c:89:38: macro "inb" passed 4 arguments, but takes just 1

drivers/media/video/usbvision/usbvision-i2c.c:173:53: macro "inb" passed 4 arguments, but takes just 1

drivers/media/video/usbvision/usbvision-i2c.c:179:54: macro "outb" passed 4 arguments, but takes just 2
drivers/media/video/usbvision/usbvision-i2c.c:179: warning: assignment makes integer from pointer without a cast
thanks to Andrew Morton for pointing this.
