      HID: intel_ish-hid: ipc: register more pm callbacks to support hibernation · ebeaa367
      Even Xu 提交于
      Current ISH driver only registers suspend/resume PM callbacks which don't
      support hibernation (suspend to disk). Basically after hiberation, the ISH
      can't resume properly and user may not see sensor events (for example: screen
      		rotation may not work).
      
      User will not see a crash or panic or anything except the following message
      in log:
      
      	hid-sensor-hub 001F:8086:22D8.0001: timeout waiting for response from ISHTP device
      
      So this patch adds support for S4/hiberbation to ISH by using the
      SIMPLE_DEV_PM_OPS() MACRO instead of struct dev_pm_ops directly. The suspend
      and resume functions will now be used for both suspend to RAM and hibernation.
      
      If power management is disabled, SIMPLE_DEV_PM_OPS will do nothing, the suspend
      and resume related functions won't be used, so mark them as __maybe_unused to
      clarify that this is the intended behavior, and remove #ifdefs for power
      management.

      HID: steam: use hid_device.driver_data instead of hid_set_drvdata() · 4bff980f
      Rodrigo Rivas Costa 提交于
      When creating the low-level hidraw device, the reference to steam_device
      was stored using hid_set_drvdata(). But this value is not guaranteed to
      be kept when set before calling probe. If this pointer is reset, it
      crashes when opening the emulated hidraw device.
      
      It looks like hid_set_drvdata() is for users "avobe" this hid_device,
      while hid_device.driver_data it for users "below" this one.
      
      In this case, we are creating a virtual hidraw device, so we must use
      hid_device.driver_data.
