      platform/x86: intel_menlow: avoid null pointer deference error · 92a74ce3
      Young Xiao authored
      Fix a null pointer deference by acpi_driver_data() if device is
      null (dereference before check). We should only set cdev and check
      this is OK after we are sure device is not null.

      platform/x86: mlx-platform: Fix parent device in i2c-mux-reg device registration · fa882fc8
      Vadim Pasternak authored
      Fix the issue found while running kernel with the option
      CONFIG_DEBUG_TEST_DRIVER_REMOVE.
      Driver 'mlx-platform' registers 'i2c_mlxcpld' device and then registers
      few underlying 'i2c-mux-reg' devices:
      	priv->pdev_i2c = platform_device_register_simple("i2c_mlxcpld", nr,
      							 NULL, 0);
      	...
      	for (i = 0; i < ARRAY_SIZE(mlxplat_mux_data); i++) {
      		priv->pdev_mux[i] = platform_device_register_resndata(
      						&mlxplat_dev->dev,
      						"i2c-mux-reg", i, NULL,
      						0, &mlxplat_mux_data[i],
      						sizeof(mlxplat_mux_data[i]));
      
      But actual parent of "i2c-mux-reg" device is priv->pdev_i2c->dev and
      not mlxplat_dev->dev.
      Patch fixes parent device parameter in a call to
      platform_device_register_resndata() for "i2c-mux-reg".
      
      It solves the race during initialization flow while 'i2c_mlxcpld.1' is
      removing after probe, while 'i2c-mux-reg.0' is still in probing flow:
      'i2c_mlxcpld.1'	flow:	probe -> remove -> probe.
      'i2c-mux-reg.0'	flow:		  probe -> ...

      platform/x86: intel-vbtn: Report switch events when event wakes device · 89ae3a07
      Mathew King authored
      When a switch event, such as tablet mode/laptop mode or docked/undocked,
      wakes a device make sure that the value of the swich is reported.
      Without when a device is put in tablet mode from laptop mode when it is
      suspended or vice versa the device will wake up but mode will be
      incorrect.
      
      Tested by suspending a device in laptop mode and putting it in tablet
      mode, the device resumes and is in tablet mode. When suspending the
      device in tablet mode and putting it in laptop mode the device resumes
      and is in laptop mode.

      Platform: OLPC: Add a config menu category for XO 1.75 · 4e6d2739
      Lubomir Rintel authored
      Randy Dunlap says:
      
        drivers/platform/olpc/Kconfig needs to use "menuconfig" like all of the
        other Kconfig files in drivers/platform/ so that its menu is listed in
        the correct place in *config interfaces.
      
      Otherwise he's sad.

      Adding the dependency seems like a more reasonable thing compared to
      ifdef-ing the bits, as if one has an XO-1.75 they almost certainly want
      a baterry and AC adapter support.
