When a symbol is selected that has extra dependencies,
anything that selects it must have the same dependencies.
With the added CONFIG_DRM reference from I2C_HID_CORE,
this broke a couple of drivers that now also depend
on DRM:

WARNING: unmet direct dependencies detected for I2C_HID_CORE
  Depends on [m]: HID_SUPPORT [=y] && I2C_HID [=y] && (DRM [=m] || !DRM [=m])
  Selected by [y]:

  - I2C_HID_OF_GOODIX [=y] && HID_SUPPORT [=y] && I2C_HID [=y] && OF [=y]

x86_64-linux-ld: vmlinux.o: in function `i2c_hid_core_probe':
(.text+0xfc8da0): undefined reference to `drm_is_panel_follower'

Add the corresponding DRM||!DRM dependencies on each one that
is affected.

This makes sense. Thanks for the fix!

I'm happy to land this in drm-misc-next (where the original patch
landed), but I'd prefer an Ack from Benjamin first, if possible. If
this is still outstanding tomorrow I'll land it anyway since it's a
small fix and he Acked the commit that this is fixing.
