V4L/DVB (4954): Fix: On ia64, i2c adap->inb/adap->outb are wrongly evaluated
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: In function `try_read_address': drivers/media/video/usbvision/usbvision-i2c.c:89: warning: assignment makes integer from pointer without a cast drivers/media/video/usbvision/usbvision-i2c.c:85: warning: unused variable `buf' 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: In function `usb_xfer': drivers/media/video/usbvision/usbvision-i2c.c:173: warning: assignment makes integer from pointer without a cast 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.
