[PATCH 2/4] drivers/message/i2o/i2o_block.c: drop negativity check of unsigned long arg

[Andrey Utkin]

[linux-3.16-rc5/drivers/message/i2o/i2o_block.c:674]: (style) Checking if
unsigned variable 'arg' is less than zero.

Source code is

        if (arg < 0 || arg > CACHE_SMARTFETCH)
            break;
but

static int i2o_block_ioctl(struct block_device *bdev, fmode_t mode,
               unsigned int cmd, unsigned long arg)
