From: Kieran Bingham Date: Tue, 17 Jan 2017 08:29:01 +0000 (+0200) Subject: drm: bridge: dw-hdmi: Remove PHY configuration resolution parameter X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1acc6bdeee1ef2ecac3ba070a403827ab8f16be5;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm: bridge: dw-hdmi: Remove PHY configuration resolution parameter The current code hard codes the call of hdmi_phy_configure() to be 8bpp and provides extraneous error checking to verify that this hardcoded value is correct. Simplify the implementation by removing the argument.
