Dear Rafael, This is devfreq-fixes pull request for v5.19-rc5. I add detailed description of this pull request on the following tag. Please pull devfreq with following updates. Best Regards, Chanwoo Choi The following changes since commit 03c765b0e3b4cb5063276b086c76f7a612856a9a: Linux 5.19-rc4 (2022-06-26 14:22:10 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux.git tags/devfreq-fixes-for-5.19-rc5 for you to fetch changes up to f08fe6fcbe13f83558ecccc4acaf5af3dce71a1f: PM / devfreq: passive: revert an editing accident in SPDX-License line (2022-06-30 05:11:17 +0900) ---------------------------------------------------------------- Update devfreq for 5.19-rc5 Detailed description for this pull request: 1. Fix devfreq passive governor issue when cpufreq policy are not ready during kernel booting because some cpus turn on after kernel booting or others. - Re-initialize the vairables of struct devfreq_passive_data when PROBE_DEFER happen when cpufreq_get_returns NULL - Use dev_err_probe to mute warning when PROBE_DEFER - Fix cpufreq passive unregister erroring on PROBE_DEFER by using the allocated parent_cpu_data list to free resouce instead of for_each_possible_cpu. - Remove duplicate cpufreq passive unregister and warning when PROBE_DEFER - Use HZ_PER_KZH macro in units.h - Fix wrong indentation in SPDX-License line 2. Fix reference count leak of exynos-ppmu.c by using of_node_put() 3. Rework freq_table to be local to devfreq struct - struct devfreq_dev_profile includes freq_table array to store the supported frequencies. If devfreq driver doesn't initialize the freq_table, devfreq core allocate the memory and initialize the freq_table. On a devfreq PROBE_DEFER, the freq_table in the driver profile struct, is never reset and may be leaved in an undefined state. To fix this and correctly handle PROBE_DEFER, use a local freq_table and max_state in the devfreq struct. ---------------------------------------------------------------- Christian Marangi (5): PM / devfreq: Fix kernel panic with cpu based scaling to passive gov PM / devfreq: Mute warning on governor PROBE_DEFER PM / devfreq: Fix cpufreq passive unregister erroring on PROBE_DEFER PM / devfreq: Rework freq_table to be local to devfreq struct PM / devfreq: Fix kernel warning with cpufreq passive register fail Lukas Bulwahn (1): PM / devfreq: passive: revert an editing accident in SPDX-License line Miaoqian Lin (1): PM / devfreq: exynos-ppmu: Fix refcount leak in of_get_devfreq_events Yicong Yang (1): PM / devfreq: passive: Use HZ_PER_KHZ macro in units.h drivers/devfreq/devfreq.c | 76 ++++++++++++++++++------------------- drivers/devfreq/event/exynos-ppmu.c | 8 +++- drivers/devfreq/governor_passive.c | 62 +++++++++++++----------------- include/linux/devfreq.h | 5 +++ 4 files changed, 75 insertions(+), 76 deletions(-)
