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.
