[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.
