Subject: apple-gmux: Fix up the suspend/resume patch
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=a2f01a899347fd97cb18094e5a55640cab552818;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

apple-gmux: Fix up the suspend/resume patch

I incorporated the wrong version of the suspend/resume patch for gmux,
and so lost David Woodhouse's fix to leave the backlight level unchanged
over suspend/resume. This fixes it up to v2.
