In current driver everytime we memcpy 4 bytes to the dest memory regardless of the remaining length. This patch adds checking the remaining length before memcpy. If the length is shorter than 4 bytes, memcpy the actual length of data to the dest memory.

V7:

• Fix type of "size" and so "size -= 4" is also fixed.
• Not use min() to avoid a compile warning of type cast.

V6:

• Use min() to simplify code.

V2-V5:

• No change.
