pm33xx.c: omap_rtc NULL dereferencing fixed #279

Open SergeySheleg opened 1 year ago

On some board designs rtc is turned off so rtc node in devicetree has status = "disabled". In this case(according to am33xx_pm_rtc_setup) rtc-only mode is disabled and omap_rtc remains NULL. However, standby mode is still available. Implementation of am33xx_pm_end in vanilla kernel 5.2+ causes NULL dereferencing of omap_rtc for such boards. This patch fixes that.
