Subject: drm/tegra: dc: Remove unused function
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3774363c75fa32cfb415df14b362e0d426418e93;p=linux-beck.git

drm/tegra: dc: Remove unused function

The tegra_dc_setup_clock() function is unused after the conversion to
atomic mode-setting, so remove it.
