[PATCH] drm/i915: Don't try to use negative pll_id.

[PATCH] drm/i915: Don't try to use negative pll_id.

[Rodrigo Vivi]

It is unlikely we are getting the -1 here.
But if we propagate that pll_id -1 to the rest of the code
we might have funny calculations on link_clock and who
knows what registers we end up accessing.

Better to protect the code.

Also better with errno number instead of generic -1.

Don't we have the dpll state already read out?

crtc_state->dll_hw_state.cfgcr0 etc.?

The function intel_get_shared_dpll_id() already has this WARN_ON:
if (WARN_ON(pll < dev_priv->shared_dplls))
and it return pll_id = (pll - dev_priv->shared_dplls);
So shouldnt this already throw a warning in case pll < dev_priv->shared_dplls eventually
resulting into a negative pll_id?

oh! we do!
Also during calc_wrpll_link we should be using this,
shouldn't we?!

Probably my bad when doing this code looking to skl code...

Same thing on skl case, right?!

On all platforms I'd say. This is all probably just leftovers from before
we had the dpll manager.

I suspect we should just move all these foo_calc_wrpll_link() etc.
functions into the dpll manager. Not sure if we could just directly
fill out the port_clock in the dpll manager actually. Hmm. I guess not
in the .get_hw_state() at least since we don't pass the full crtc state
there. But we could perhaps have some kind of .clock_get() function
that'd be similar to the i9xx/vlv/chv_clock_get(), except we'd just call
it from the DDI code where we currently call these hand rolled
functions.

yeap, we through a warning and return -1.

Then we use the -1 to do some reg access and bits...
