Offset of kmd_arg is expected to be in words (As we are feeding the offset in word size from UMD lib). Whereas the validity check function treats it as bytes which is wrong. This might lead to crash if lager offset is feed from UMD via ioctl call. Change-Id: I7de76cea5abe9a34d4194d041af7a3af7550d86d Signed-off-by: Aniruddh Sharma <quic_anirshar@quicinc.com>
