    Hello All ,
    I was trying to add a new ioctl cnd like
    #define HDLCMODE _IOR('6',0xF,int)
    when i try to uprintf the data which was sent from the user-space in the
    device-driver-ioctl-routine i'll get a different value than which is passed.
    Can anybody please tell me why this is happening . I pass the address of
    integer from the user space as third arg to the ioctl call .
    thanks and regards,
    Rashmi.N.S
