ARM: at91: pm: remove pm_bu initialization in at91_pm_backup_init() (1e1f808f) · Commits · 戴 / test

There is no need to initialize pm_bu since it is used only if backup mode is selected. In case backup mode initialization fails (which means pm_bu is invalid) the ULP0 mode will be selected. Signed-off-by:
