This series updates all such drivers to stop validating the cpufreq table directly and let only the core handle it. It depends on the previous series [1] and two cleanup patches [2][3] and is rebased over 4.16-rc3. It is already tested by the 0-day testing infrastructure and no issues were reported. --- viresh [1] https://lkml.kernel.org/r/bd8c6133ad0bdd56c936802bcf26878d7cbdb679.1519279148.git.viresh.kumar@linaro.org [2] https://lkml.kernel.org/r/77d470741dab32c2076a35253b9c0c2f0136583b.1519293292.git.viresh.kumar@linaro.org [3] https://lkml.kernel.org/r/6b737a9c285840b4b2036fa51b692ee835664ec8.1519358505.git.viresh.kumar@linaro.org Viresh Kumar (27): cpufreq: imx6q: Find max freq from frequency table itself cpufreq: Don't validate cpufreq table from cpufreq_generic_init() cpufreq: acpi: Don't validate the frequency table twice cpufreq: arm_big_little: Don't validate the frequency table twice cpufreq: blackfin: Don't validate the frequency table twice cpufreq: brcmstb: Don't validate the frequency table twice cpufreq: cpufreq-dt: Don't validate the frequency table twice cpufreq: e_powersaver: Don't validate the frequency table twice cpufreq: elanfreq: Don't validate the frequency table twice cpufreq: ia64-acpi: Don't validate the frequency table twice cpufreq: longhaul: Don't validate the frequency table twice cpufreq: mediatek: Don't validate the frequency table twice cpufreq: p4-clockmod: Don't validate the frequency table twice cpufreq: powernow: Don't validate the frequency table twice cpufreq: powerenv: Don't validate the frequency table twice cpufreq: ppc_cbe: Don't validate the frequency table twice cpufreq: pxa: Don't validate the frequency table twice cpufreq: qoirq: Don't validate the frequency table twice cpufreq: s3c24xx: Don't validate the frequency table twice cpufreq: sc520: Don't validate the frequency table twice cpufreq: scpi: Don't validate the frequency table twice cpufreq: sfi: Don't validate the frequency table twice cpufreq: sh: Don't validate the frequency table twice cpufreq: sparc: Don't validate the frequency table twice cpufreq: speedstep: Don't validate the frequency table twice cpufreq: tegra186: Don't validate the frequency table twice cpufreq: Drop cpufreq_table_validate_and_show() Documentation/cpu-freq/core.txt | 12 +++++------- Documentation/cpu-freq/cpu-drivers.txt | 6 ++---- drivers/cpufreq/acpi-cpufreq.c | 20 +++++++++++--------- drivers/cpufreq/arm_big_little.c | 9 +-------- drivers/cpufreq/blackfin-cpufreq.c | 3 ++- drivers/cpufreq/brcmstb-avs-cpufreq.c | 6 +----- drivers/cpufreq/cpufreq-dt.c | 8 +------- drivers/cpufreq/cpufreq.c | 9 +-------- drivers/cpufreq/e_powersaver.c | 8 +------- drivers/cpufreq/elanfreq.c | 3 ++- drivers/cpufreq/freq_table.c | 14 -------------- drivers/cpufreq/ia64-acpi-cpufreq.c | 7 +------ drivers/cpufreq/imx6q-cpufreq.c | 7 ++++--- drivers/cpufreq/longhaul.c | 3 ++- drivers/cpufreq/mediatek-cpufreq.c | 11 +---------- drivers/cpufreq/p4-clockmod.c | 3 ++- drivers/cpufreq/powernow-k6.c | 3 ++- drivers/cpufreq/powernow-k7.c | 3 ++- drivers/cpufreq/powernow-k8.c | 10 +--------- drivers/cpufreq/powernv-cpufreq.c | 11 +++-------- drivers/cpufreq/ppc_cbe_cpufreq.c | 5 ++--- drivers/cpufreq/pxa2xx-cpufreq.c | 4 ++-- drivers/cpufreq/pxa3xx-cpufreq.c | 4 +++- drivers/cpufreq/qoriq-cpufreq.c | 13 ++----------- drivers/cpufreq/s3c24xx-cpufreq.c | 5 +---- drivers/cpufreq/sc520_freq.c | 3 ++- drivers/cpufreq/scpi-cpufreq.c | 10 +--------- drivers/cpufreq/sfi-cpufreq.c | 3 ++- drivers/cpufreq/sh-cpufreq.c | 22 ++++++++++++---------- drivers/cpufreq/sparc-us2e-cpufreq.c | 3 ++- drivers/cpufreq/sparc-us3-cpufreq.c | 3 ++- drivers/cpufreq/speedstep-centrino.c | 4 ++-- drivers/cpufreq/speedstep-ich.c | 4 +++- drivers/cpufreq/speedstep-smi.c | 4 +++- drivers/cpufreq/tegra186-cpufreq.c | 2 +- include/linux/cpufreq.h | 2 -- 36 files changed, 85 insertions(+), 162 deletions(-)
