platform/chrome: Use proper protocol transfer function

2018-03-24T09:58:47+00:00

[ Upstream commit d48b8c58c57f6edbe2965f0a5f62c5cf9593ca96 ]

pkt_xfer should be used for protocol v3, and cmd_xfer otherwise. We had
one instance of these functions correct, but not the second, fall-back
case. We use the fall-back only when the first command returns an
IN_PROGRESS status, which is only used on some EC firmwares where we
don't want to constantly poll the bus, but instead back off and
sleep/retry for a little while.

cros_ec: fix nul-termination for firmware build info

2018-03-24T09:58:47+00:00

[ Upstream commit 50a0d71a5d20e1d3eff1d974fdc8559ad6d74892 ]

As gcc-8 reports, we zero out the wrong byte:

drivers/platform/chrome/cros_ec_sysfs.c: In function 'show_ec_version':
drivers/platform/chrome/cros_ec_sysfs.c:190:12: error: array subscript 4294967295 is above array bounds of 'uint8_t[]' [-Werror=array-bounds]

This changes the code back to what it did before changing to a
zero-length array structure.

Asus laptop X302UA starts up with Wi-Fi disabled,
without a way to enable it. Set wapf=4 to fix the problem.

platform/x86: hp-wmi: Do not shadow error values

2017-11-15T16:13:11+00:00

commit d313876925f3e7a480a02773fd333bcab9202d5e upstream.

All the helper functions (i.e. hp_wmi_dock_state, hp_wmi_tablet_state,
...) using hp_wmi_perform_query to perform an HP WMI query shadow the
returned value in case of error.

We return -EINVAL only when the HP WMI query returns a positive value
(the specific error code) to not mix this up with the actual value
returned by the helper function.

platform/x86: hp-wmi: Fix detection for dock and tablet mode

2017-11-15T16:13:11+00:00

commit 298747b7579f5bbbced793d997b333fd10a24921 upstream.

The current driver code is not checking for the error values returned by
'hp_wmi_dock_state()' and 'hp_wmi_tablet_state()' before passing the
returned values down to 'input_report_switch()'. This error code is
being translated to '1' in the input subsystem, reporting the wrong
status.

The biggest problem caused by this issue is that several laptops are
wrongly reported by the driver as docked, preventing them to be put to
sleep using the LID (and in most cases they are not even dockable).

With this patch we create the report switches only if we are able to
read the dock and tablet mode status correctly from ACPI.

platform/x86: intel_mid_thermal: Fix module autoload

2017-11-08T09:06:30+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
