ANDROID: tegra: cl_dvfs arbitrary kernel memory access Remove "/sys/kernel/debug/clock/dfll_cpu/cl_dvfs/registers" node as this allows a root attacker to arbitrarily adjust kernel to their whim beyond what root alone can do. i.e. bypass drm. NB: User builds do not expose debugfs Signed-off-by: Mark Salyzyn <salyzyn@google.com> Bug: 29518457 Change-Id: I6de19064f1748e57c86873e0d8578a627fba0efc
