2013-04-12[media] s5p-mfc: Add support for EOS command and EOS event in video decoderKamil Debski1-1/+9
Add support for V4L2_DEC_CMD_STOP command which will instruct MFC device to finish decoding and release all remaining frames kept for reference to the user. After dequeueing last decoded frame the driver will generate an V4L2_EVENT_EOS event.

2013-01-06[media] s5p-mfc: Fix an error checkSachin Kamat1-2/+2
Checking unsigned variable for negative value always returns false. Hence make this value signed as we expect it to be negative too. Fixes the following smatch warning: drivers/media/platform/s5p-mfc/s5p_mfc_opr_v6.c:572 s5p_mfc_set_enc_ref_buffer_v6() warn: unsigned 'buf_size1' is never less than zero.
