Subject: [PATCH] Some Samsung laptops with Fn+Fx key release not working
[PATCH] Some Samsung laptops with Fn+Fx key release not working
Some new Samsung laptops doesn't send key-release signal of the
volume key to the OS, it's quite hard to change the volume by
using Fn+Fx, so I decode the DMI and add several samsung machines
to the forced_release_keys table in order to fixed this problem.
DMI (only a part):
# dmidecode
...
Handle 0x0001, DMI type 1, 27 bytes

P.S: I have tested this patch on all these machines and It
works very well.

input/keyboard: Some Samsung laptops with Fn+Fx key release not working
Some new Samsung laptops doesn't send key-release signal to the Operating
System when we click on Fn+F[6-8], so we have to force it to release immedi-
ately after receiving the key-press signal.
