      asus-wmi: Create quirk for airplane_mode LED · a977e59c
      João Paulo Rechi Vita authored
      Some Asus laptops that have an airplane-mode indicator LED, also have
      the WMI WLAN user bit set, and the following bits in their DSDT:
      
      Scope (_SB)
      {
        (...)
        Device (ATKD)
        {
          (...)
          Method (WMNB, 3, Serialized)
          {
            (...)
            If (LEqual (IIA0, 0x00010002))
            {
              OWGD (IIA1)
              Return (One)
            }
          }
        }
      }
      
      So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
      wlan state, it drives the airplane-mode indicator LED (through the call
      to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
      (since wlan is ON), and vice-versa.
      
      This commit creates a quirk to not register a RFKill switch at all for
      these laptops, to allow the asus-wireless driver to drive the airplane
      mode LED correctly through the ASHS ACPI device. It also adds a match to
      that quirk for the Asus X555UB, which is affected by this problem.

      asus-wireless: Toggle airplane mode LED · 2c1a49c9
      João Paulo Rechi Vita authored
      In the ASHS device we have the HSWC method, which calls either OWGD or
      OWGS, depending on its parameter:
      
      	Device (ASHS)
      	{
      		Name (_HID, "ATK4002")  // _HID: Hardware ID
      		Method (HSWC, 1, Serialized)
      		{
      			If ((Arg0 < 0x02))
      			{
      				OWGD (Arg0)
      				Return (One)
      			}
      			If ((Arg0 == 0x02))
      			{
      				Local0 = OWGS ()
      				If (Local0)
      				{
      					Return (0x05)
      				}
      				Else
      				{
      					Return (0x04)
      				}
      			}
      			If ((Arg0 == 0x03))
      			{
      				Return (0xFF)
      			}
      			If ((Arg0 == 0x04))
      			{
      				OWGD (Zero)
      				Return (One)
      			}
      			If ((Arg0 == 0x05))
      			{
      				OWGD (One)
      				Return (One)
      			}
      			If ((Arg0 == 0x80))
      			{
      				Return (One)
      			}
      		}
      		Method (_STA, 0, NotSerialized)  // _STA: Status
      		{
      			If ((MSOS () >= OSW8))
      			{
      				Return (0x0F)
      			}
      			Else
      			{
      				Return (Zero)
      			}
      		}
      	}
      
      On the Asus laptops that do not have an airplane mode LED, OWGD has an
      empty implementation and OWGS simply returns 0. On the ones that have an
      airplane mode LED these methods have the following implementation:
      
      	Method (OWGD, 1, Serialized)
      	{
      		SGPL (0x0203000F, Arg0)
      		SGPL (0x0203000F, Arg0)
      	}
      
      	Method (OWGS, 0, Serialized)
      	{
      		Store (RGPL (0x0203000F), Local0)
      		Return (Local0)
      	}
      
      Where OWGD(1) sets the airplane mode LED ON, OWGD(0) set it off, and
      OWGS() returns its state.
      
      This commit exposes the airplane mode indicator LED to userspace under
      the name asus-wireless::airplane, so it can be driven according to
      userspace's policy.

       "A new bunch of GPIO fixes for v4.7.
      
        This time I am very grateful that Ricardo Ribalda Delgado went in and
        fixed my stupid refcounting mistakes in the removal path for GPIO
        chips.  I had a feeling something was wrong here and so it was.  It
        exploded on OMAP and it fixes their problem.  Now it should be (more)
        solid.
      
        The rest i compilation, Kconfig and driver fixes.  Some tagged for
        stable.
      
        Summary:
      
         - Fix a NULL pointer dereference when we are searching the GPIO
           device list but one of the devices have been removed (struct
           gpio_chip pointer is NULL).
      
         - Fix unaligned reference counters: we were ending on +3 after all
           said and done.  It should be 0.  Remove an extraneous get_device(),
           and call cdev_del() followed by device_del() in gpiochip_remove()
           instead and the count goes to zero and calls the release() function
           properly.
      
         - Fix a compile warning due to a missing #include in the OF/device
           tree portions.
      
         - Select ANON_INODES for GPIOLIB, we're using that for our character
           device.  Some randconfig tests disclosed the problem.
      
         - Make sure the Zynq driver clock runs also without CONFIG_PM enabled
      
         - Fix an off-by-one error in the 104-DIO-48E driver
      
         - Fix warnings in bcm_kona_gpio_reset()"

      Pull SCSI fixes from James Bottomley:
       "Two current fixes:
      
         - one affects Qemu CD ROM emulation, which stopped working after the
           updates in SCSI to require VPD pages from all conformant devices.
      
           Fix temporarily by blacklisting Qemu (we can relax later when they
           come into compliance).
      
         - The other is a fix to the optimal transfer size.  We set up a
           minefield for ourselves by being confused about whether the limits
           are in bytes or sectors (SCSI optimal is in blocks and the queue
           parameter is in bytes).
      
           This tries to fix the problem (wrong setting for queue limits
           max_sectors) and make the problem more obvious by introducing a
           wrapper function"
