No build time dependencies.

But from the description of "atmel-hlcdc: return in case of error":
"
For HLCDC timing engine configurations bit ATMEL_HLCDC_SIP of
ATMEL_HLCDC_SR needs to be polled before applying new config.
"
I get that changing timing for the HLCDC may fail if these
patches are not applied.
So it is only to have updated hlcdc support in drm-misc-next
for further testing.
