[PATCH 2/3] PM / wakeirq: drop unused enable helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Drop the wake-irq enable and disable helpers which have not been used
since commit bed570307ed7 ("PM / wakeirq: Fix dedicated wakeirq for
drivers not using autosuspend").

Note that these functions are essentially just leftovers from the first
iteration of the wake-irq implementation where device drivers were
supposed to call these functions themselves instead of PM core (as
is also indicated by the bogus kernel doc comments).
