[PATCH] clk: sunxi-ng: common: Don't call hw_to_ccu_common on hw without common

by Frank Oltmanns

In order to set the rate range of a hw sunxi_ccu_probe calls hw_to_ccu_common() assuming all entries in desc->ccu_clks are contained in a ccu_common struct. This assumption is incorrect and, in consequence, causes invalid pointer de-references. Remove the faulty call. Instead, add one more loop that iterates over the ccu_clks and sets the rate range, if required. Fixes: b914ec33b391 ("clk: sunxi-ng: common: Support minimum and maximum rate") Reported-by: Robert J.

[PATCH] drm/lima: Mark simple_ondemand governor as softdep

by Dragan Simic

Lima DRM driver uses devfreq to perform DVFS, while using simple_ondemand devfreq governor by default. This causes driver initialization to fail on boot when simple_ondemand governor isn't built into the kernel statically, as a result of the missing module dependency and, consequently, the required governor module not being included in the initial ramdisk. Thus, let's mark simple_ondemand governor as a softdep for Lima, to have its kernel module included in the initial ramdisk. This is a rather longstanding issue that has forced distributions to build devfreq governors statically into their kernels, [1][2] or may have forced some users to introduce unnecessary workarounds. Having simple_ondemand marked as a softdep for Lima may not resolve this issue for all Linux distributions. In particular, it will remain unresolved for the distributions whose utilities for the initial ramdisk generation do not handle the available softdep information [3] properly yet. However, some Linux distributions already handle softdeps properly while generating their initial ramdisks, [4] and this is a prerequisite step in the right direction for the distributions that don't handle them properly yet.
