libhwc2.1: libdisplayinterface: override sendHistogramChannelIoctl
If control is REQUEST, call histogram_channel_request_ioctl which creates the drm event to request the histogram data. If control is CANCEL, call histogram_channel_cancel_ioctl which frees the drm event to cancel the histogram data request. Bug: 255986866 Bug: 227384721 Test: use aidl_hist_client to test multi channel histogram Change-Id: I2d87aa7e92128ac0430ae12ad3a913fc4db960b4 Signed-off-by: Leo Chen <yinchiuan@google.com>
