[RFC,4/8] PM / Domains: Lookup domain by name

Commit Message

Rickard Andersson March 22, 2013, 4:20 p.m. UTC

Make the function pm_genpd_lookup_name(..) non
static. This is done to limit the need for "name
functions" as e.g. pm_genpd_name_attach_cpuidle.
Also the name lookup takes a mutex and should not
be called when IRQ's are off. So by exporting this
function the name lookup can be done before IRQ's
are off.
