Subject: [PATCH] um: Fix build w/o CONFIG_PM_SLEEP
|
|
|
|
|
|
|
|
|
|
uml_pm_wake() is unconditionally called from the SIGUSR1 wakeup
|
|
|
|
|
handler since that's in the userspace portion of UML, and thus
|
|
|
|
|
a bit tricky to ifdef out. Since pm_system_wakeup() can always
|
|
|
|
|
be called (but may be an empty inline), also simply always have
|
|
|
|
|
uml_pm_wake() to fix the build.
