2016-03-23asus-nb-wmi: add wapf=4 quirk for ASUS X75VDOleksandr Natalenko1-0/+9

2016-03-23dell-wmi: Support new hotkeys on the XPS 13 9350 (Skylake)Andy Lutomirski1-7/+64
The XPS 13 9350 sends WMI keypress events that aren't enumerated in the DMI table. Add a table listing them. To avoid breaking things that worked before, these un-enumerated hotkeys won't be used if the DMI table maps them to something else. FWIW, it appears that the DMI table may be a legacy thing and we might want to rethink how we handle events in general. As an example, a whole lot of things map to KEY_PROG3 via the DMI table. This doesn't send keypress events for any of the new events. They appear to all be handled by other means (keyboard illumination is handled automatically and rfkill is handled by intel-hid).

2016-03-23dell-wmi: Clean up hotkey table size checkAndy Lutomirski1-2/+13
Checking the table for a minimum size of 7 bytes makes no sense: any valid hotkey table has a size that's a multiple of 4. Clean this up: replace the hardcoded header length with a sizeof and change the check to ignore an empty hotkey table. The only behavior change is that a 7-byte table (which is nonsensical) will now be treated as absent instead of as valid but empty.

2016-03-23dell-wmi: Stop storing pointers to DMI tablesAndy Lutomirski1-28/+46
The dmi_walk function maps the DMI table, walks it, and unmaps it. This means that the dell_bios_hotkey_table that find_hk_type stores points to unmapped memory by the time it gets read. I've been able to trigger crashes caused by the stale pointer a couple of times, but never on a stock kernel. Fix it by generating the keymap in the dmi_walk callback instead of storing a pointer.

Add sanity checking to ensure that we do not program load or match values that are out of range if a user requests period or duty_cycle values which are not achievable. The match value cannot be less than the load value (but can be equal), and neither can be 0xffffffff.
