Hi Paul,

Commit 1bdb542da736 ("drm/ingenic: Simplify code by using hwdescs array") caused the dma_hwdesc_phys_f{0,1} variables to be used while uninitialized in a mmio register write, which most certainly broke the ingenic-drm driver.
However, the very same patchset also submitted commit 6055466203df ("drm/ingenic: Upload palette before frame"), which restored a correct behaviour by doing the register writes in a different place in the code.
What's left of this, is just to remove the bogus register writes in the probe function.
