Subject: drm/i915: Extract bdw_get_buf_trans_edp()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a930acd91f46ad4ae15d14a8c018bb9356ef3be6;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

drm/i915: Extract bdw_get_buf_trans_edp()

Make the BDW and SKL code a bit more similar by extracting the
low vswing handling for BDW into a helper, as we already have
it like that for SKL+.
