platform-drivers-x86 for v4.15-3

Browse source 
Correct an error in the evdev protocol in asus-wireless which results in
 dropped key events in recent versions of libinput. Add a quirk for
 keyboard lighting for a specific Dell laptop. Silence a static analysis
 warning regarding unchecked return values of small kmalloc() allocations
 in dell-wmi.
 
 The following is an automated git shortlog grouped by driver:
 
 asus-wireless:
  -  send an EV_SYN/SYN_REPORT between state changes
 
 dell-laptop:
  -  Fix keyboard max lighting for Dell Latitude E6410
 
 dell-wmi:
  -  check for kmalloc() errors
