[PATCH] fbdev: Batch cmap changes at driver level
This patch adds to the fbdev interface a set_cmap callback that allow the
driver to "batch" palette changes. This is useful for drivers like
radeonfb which might require lenghtly workarounds on palette accesses, thus
allowing to factor out those workarounds efficiently.
