With this patch, ep0 transfer breaks. it because the 'enabled' of ep0 is not set. Ep0
is not enabled by usb_ep_enable, but in UDC driver. So there need another patch
to set ep0's flag also.

DRM color manager supports these color properties:
1. "ctm": Color transformation matrix property, where a
color transformation matrix of 9 correction values gets
applied as correction.
2. "palette_before_ctm": for corrections which get applied
beore color transformation matrix correction.
3. "palette_after_ctm": for corrections which get applied
after color transformation matrix correction.
These color correction capabilities may differ per platform, supporting
various different no. of correction coefficients. So DRM color manager
support few properties using which a user space can query the platform's
capability, and prepare color correction accordingly.
These query properties are:
1. cm_coeff_after_ctm_property
2. cm_coeff_before_ctm_property
(CTM is fix to 9 coefficients across industry)
