From 245f586876eefc55438f0d65856fbe15de8dadca Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 30 Nov 2015 16:23:42 +0200 Subject: [PATCH] drm/i915: Fix VBT backlight Hz to PWM conversion for PNV MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Convert the MHz number coming from intel_rawclk() into Hz in i9xx_hz_to_pwm() on PNV. Otherwise we'll get something totally bogus as a result.
