commit a66b2e (cpufreq: Preserve sysfs files across suspend/resume) has
|
||||
unfortunately caused several things in the cpufreq subsystem to break subtly
|
||||
after a suspend/resume cycle.
|
||||
|
||||
The intention of that patch was to retain the file permissions of the
|
||||
cpufreq related sysfs files across suspend/resume. To achieve that, the commit
|
||||
completely removed the calls to cpufreq_add_dev() and __cpufreq_remove_dev()
|
||||
during suspend/resume transitions. But the problem is that those functions
|
||||
do 2 kinds of things:
|
||||
1. Low-level initialization/tear-down that are critical to the correct
|
||||
functioning of cpufreq-core.
|
||||
2. Kobject and sysfs related initialization/teardown.
|
||||
|
||||
Ideally we should have reorganized the code to cleanly separate these two
|
||||
responsibilities, and skipped only the sysfs related parts during
|
||||
suspend/resume. Since we skipped the entire callbacks instead (which also
|
||||
included some CPU and cpufreq-specific critical components), cpufreq
|
||||
subsystem started behaving erratically after suspend/resume.
|
||||
|
||||
So revert the commit to fix the regression. We'll revisit and address the
|
||||
original goal of that commit separately, since it involves quite a bit of
|
||||
careful code reorganization and appears to be non-trivial.
|
||||
|
||||
(While reverting the commit, note that another commit f51e1eb "cpufreq:
|
||||
Fix cpufreq regression after suspend/resume" already reverted part of the
|
||||
original set of changes. So revert only the remaining ones).
