Subject: [PATCH v2] drm/i915/bxt: Fix off-by-one error in Broxton PLL IDs
Date: Mon, 14 Mar 2016 19:55:34 +0200	[thread overview]
Message-ID: <1457978134-12362-1-git-send-email-imre.deak@intel.com> (raw)
In-Reply-To: <1457977942-11772-1-git-send-email-imre.deak@intel.com>

After the commit below the Broxton PLL IDs had an off-by-one error, so
fix this up. Also add a missing brace at intel_shared_dpll_init(), it
happened to compile only due to the way the IS_BROXTON macro is defined.

v2:
- remove debugging left-over

Fixes: a3c988ea068c ("drm/i915: Make SKL/KBL DPLL0 managed by the shared dpll code")
