Subject: [PATCH] drm/i915: Don't pass clock to DDI PLL select functions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
All the *_ddi_pll_select() functions get passed the port_clock and pipe
config as parameters. We only need to pass the pipe config, and the
functions can dig up the port_clock themselves.
