Can you explain the purpose of this change please?
I guess it's because the sysctrl_dev is already initialised when
registering the power_off handler, so there isn't a way to call the
above function with a NULL sysctrl_dev. Probably even with the original
code you didn't need this check (after some race fix in
ab8500_sysctrl_remove but races is one of the things Guenter's patches
try to address).
Sounds reasonable, although I think this change should be part of
another patch.
Sure, no problem. I'll split this into two patches.
Since we are at it, any idea what to do with the restart function
in the same file ? It is not used anywhere.
