Thanks for the report! Ugh, I guess I forgot that even though DRM_PANEL is bool, it gets bundled up into all of DRM which can be a module. Assuming that this series looks mostly the same in the next version, I'll plan to add this: depends on DRM || !DRM # if DRM=m, this can't be 'y' ...to each of the i2c-hid subclasses. -Doug
