PM / domains: Fix 'may be used uninitialized' build warning
This patch fixes the following gcc warning: drivers/base/power/domain.c: In function ‘genpd_runtime_resume’: drivers/base/power/domain.c:642:14: warning: ‘time_start’ may be used uninitialized in this function [-Wmaybe-uninitialized] elapsed_ns = ktime_to_ns(ktime_sub(ktime_get(), time_start) The same problem (in another function in this same file) was fixed in commit d33d5a6c88fc (avoid spurious "may be used uninitialized" warning) Signed-off-by: Augusto Mecking Caringi <augustocaringi@gmail.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
