Hi,
This is a continuation of my old patchset from 2019. [1] Back then, few drivers set driver_override wrong. I fixed Exynos in a different way after discussions. QCOM NGD was not fixed and a new user appeared - IMX SCU.
It seems "char *" in driver_override looks too consty, so we tend to make a mistake of storing there string literals.
Changes of latest since v1 (not the old 2019 solution): ======================================================= https://lore.kernel.org/all/708eabb1-7b35-d525-d4c3-451d4a3de84f@rasmusville... 1. Add helper for setting driver_override. 2. Use the helper.
Dependencies (and stable): ========================== 1. All patches, including last three fixes, depend on first patch introducing the helper. 2. The last three commits - fixes - are probably not backportable directly, because of this dependency. I don't know how to express it here, since stable-kernel-rules.rst mentions only commits as possible dependencies.
