New subject: [Linux-stable-mirror] [PATCH] cpufreq: mediatek: Add mediatek related projects into blacklist

23 Jan 2018

From: Sean Wang sean.wang@mediatek.com
commit 6066998cbd2b1012a8d5bc9a2957cfd0ad53150e upstream.
commit edeec420de24 ("cpufreq: dt-platdev: Automatically create cpufreq
device with OPP v2") not added MediaTek SoCs to the blacklist that would
lead to cause an occasional hang or unexpected behaviors on related boards
as kernelci reported and complained on [1] specifically for 4.14 and 4.15
tree.
For those reasons, add MediaTek SoCs into cpufreq-dt blacklist and wish
the patch be applied to 4.14 and 4.15 tree to allow kernelci able to
complete following automated kernel testing.
