default:
The changes made for the cx23888 caused regressions in the analog support for cx23885/cx23887 based boards (partly due to changes in the locations of the hue/saturation controls). As a result the wrong registers were being overwritten. Add code to use the correct registers if it's a cx23888 Validated with the following boards: HVR-1800 retail (0070:7801) HVR-1800 OEM (0070:7809) HVR-1850 retail (0070:8541) Thanks to Steven Toth and Hauppauge for loaning me various boards to regression test with.
