ARM: davinci: dm646x evm: wrong register used in setup_vpif_input_channel_mode
commit 83713fc9373be2e943f82e9d36213708c6b0050e upstream.
The function setup_vpif_input_channel_mode() used the VSCLKDIS register
instead of VIDCLKCTL. This meant that when in HD mode videoport channel 0
used a different clock from channel 1.
Clearly a copy-and-paste error.
