platform/x86: asus-nb-wmi: Add keymap entry for lid flip action on UX360

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.

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.
