Booting from /dev/mtdblock/0

[Jim Thompson]

Its a one-line fix.

    static release_t mtdblock_release(struct inode *inode, struct file *file)
    {
	    int dev;
	    struct mtdblk_dev *mtdblk;
	    DEBUG(MTD_DEBUG_LEVEL1, "mtdblock_release\n", inode);

	    if (inode == NULL)
		    release_return(-ENODEV);

    #if 0
	    invalidate_device(inode->i_rdev, 1);
    #endif
