platform/x86: intel_mid_powerbtn: Take a copy of ddata

2020-02-14T21:34:12Z

commit 5e0c94d3aeeecc68c573033f08d9678fecf253bd upstream. The driver gets driver_data from memory that is marked as const (which is probably put to read-only memory) and it then modifies it. This likely causes some sort of fault to happen. Fix this by taking a copy of the structure.

platform/x86: intel_scu_ipc: Fix interrupt support

2020-02-11T12:35:15Z

commit e48b72a568bbd641c91dad354138d3c17d03ee6f upstream. Currently the driver has disabled interrupt support for Tangier but actually interrupt works just fine if the command is not written twice in a row. Also we need to ack the interrupt in the handler.

platform/x86: GPD pocket fan: Allow somewhat lower/higher temperature limits

2020-02-05T21:22:45Z

[ Upstream commit 1f27dbd8265dbb379926c8f6a4453fe7fe26d7a3 ] Allow the user to configure the fan to turn on / speed-up at lower thresholds then before (20 degrees Celcius as minimum instead of 40) and likewise also allow the user to delay the fan speeding-up till the temperature hits 90 degrees Celcius (was 70).

platform/x86: dell-laptop: disable kbd backlight on Inspiron 10xx

2020-02-01T09:34:47Z

[ Upstream commit 10b65e2915b2fcc606d173e98a972850101fb4c4 ] This patch adds a quirk disabling keyboard backlight support for the Dell Inspiron 1012 and 1018. Those models wrongly report supporting keyboard backlight control features (through SMBIOS tokens) even though they're not equipped with a backlit keyboard. This led to broken controls being exposed through sysfs by this driver which froze the system when used.

[ Upstream commit 856a0a6e2d09d31fd8f00cc1fc6645196a509d56 ] This is caused by dereferencing 'dev_data' after put_device() in the telem_device_remove() function.

platform/x86: GPD pocket fan: Use default values when wrong modparams are given

2020-01-17T18:48:43Z

commit 6ae01050e49f0080ae30575d9b45a6d4a3d7ee23 upstream. Use our default values when wrong module-parameters are given, instead of refusing to load. Refusing to load leaves the fan at the BIOS default setting, which is "Off". The CPU's thermal throttling should protect the system from damage, but not-loading is really not the best fallback in this case. This commit fixes this by re-setting module-parameter values to their defaults if they are out of range, instead of failing the probe with -EINVAL.

platform/mellanox: fix potential deadlock in the tmfifo driver

2020-01-17T18:48:42Z

commit 638bc4ca3d28c25986cce4cbad69d9b8abf1e434 upstream. This commit fixes the potential deadlock caused by the console Rx and Tx processing at the same time. Rx and Tx both take the console and tmfifo spinlock but in different order which causes potential deadlock. The fix is to use different tmfifo spinlock for Rx and Tx since they protect different resources and it's safe to split the lock. Below is the reported call trace when copying/pasting large string in the console.
