platform/x86: intel_mid_thermal: Fix module autoload

2017-11-08T09:03:49+00:00

[ Upstream commit a93151a72061e944a4915458b1b1d6d505c03bbf ]

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.

Export the module alias information using the MODULE_DEVICE_TABLE() macro.

Before this patch:

$ modinfo drivers/platform/x86/intel_mid_thermal.ko | grep alias
$

After this patch:

$ modinfo drivers/platform/x86/intel_mid_thermal.ko | grep alias
alias:          platform:msic_thermal

platform/x86: acer-wmi: setup accelerometer when machine has appropriate notify event

2017-04-22T05:15:01+00:00

commit 98d610c3739ac354319a6590b915f4624d9151e6 upstream.

The accelerometer event relies on the ACERWMID_EVENT_GUID notify.
So, this patch changes the codes to setup accelerometer input device
when detected ACERWMID_EVENT_GUID. It avoids that the accel input
device created on every Acer machines.

In addition, patch adds a clearly parsing logic of accelerometer hid
to acer_wmi_get_handle_cb callback function. It is positive matching
the "SENR" name with "BST0001" device to avoid non-supported hardware.

hp-wmi: Fix wifi cannot be hard-unblocked

2016-08-22T16:23:01+00:00

[ Upstream commit fc8a601e1175ae351f662506030f9939cb7fdbfe ]

Several users reported wifi cannot be unblocked as discussed in [1].
This patch removes the use of the 2009 flag by BIOS but uses the actual
WMI function calls - it will be skipped if WMI reports unsupported.

ideapad-laptop: Add ideapad Y700 (15) to the no_hw_rfkill DMI list

2016-04-18T12:49:39+00:00

[ Upstream commit 4db9675d927a71faa66e5ab128d2390d6329750b ]

Some Lenovo ideapad models lack a physical rfkill switch.
On Lenovo models ideapad Y700 Touch-15ISK and ideapad Y700-15ISK,
ideapad-laptop would wrongly report all radios as blocked by
hardware which caused wireless network connections to fail.

Add these models without an rfkill switch to the no_hw_rfkill list.

intel_scu_ipcutil: underflow in scu_reg_access()

2016-03-02T20:18:53+00:00

[ Upstream commit b1d353ad3d5835b16724653b33c05124e1b5acf1 ]

"count" is controlled by the user and it can be negative.  Let's prevent
that by making it unsigned.  You have to have CAP_SYS_RAWIO to call this
function so the bug is not as serious as it could be.
