4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sudip Mukherjee <sudipm.mukherjee@xxxxxxxxx>
commit 59921b239056fb6389a865083284e00ce0518db6 upstream.
hw->DACreg has a size of 80 bytes and MGADACbpp32 has 21. So when
memcpy copies MGADACbpp32 to hw->DACreg it copies 80 bytes but
only 21 bytes are valid.
