      ARM: OMAP4: cpuidle: fix: call cpu_cluster_pm_exit conditionally · 78350271
      Vladimir Murzin 提交于
      We call cpu_cluster_pm_enter for dev->cpu == 0 only, but
      cpu_cluster_pm_exit called without that check.
      
      Because of that unhandled page fault may happen:

      It is supposed that sar_base is initialized in irq_save_context, which
      is called on CPU_CLUSTER_PM_ENTER notification. If this notification
      has been missed and CPU_CLUSTER_PM_EXIT is received sar_base is NULL.
      
      Fix it by calling CPU_CLUSTER_PM_{ENTER,EXIT} under the same condition.

      The driver core clears the driver data to NULL after device_release

      ARM: OMAP: fix return value check in omap_device_build_from_dt() · 4cf9cf89

      In case of error, the function omap_device_alloc() returns ERR_PTR()
      and never returns NULL. The NULL test in the return value check
      should be replaced with IS_ERR().

      ARM: OMAP4: Fix clock_get error for GPMC during boot · 2cfeed31
      Tony Lindgren 提交于
      Looks like we still have the legacy clock alias name for
      omap4 GPMC (General Purpose Memory Controller), so let's
      fix it for the device tree naming. There's no need to keep
      the legacy naming as omap4 is DT only nowadays.
      
      Without this fix we get the following error while booting:
