Dear ACPI developers,

[1.] One line summary of the problem:
After upgrading the kernel toggling the hardware radio switch doesn't
generate an acpi event anylonger.

[2.] Full description of the problem/report:
I use a customized acpi event script to disable bluetooth on my
Thinkpad x220, if I toggle the hardware wifi switch (not Fn+F5 but a
physical switch). This used to work fine with v3.11, however it
stopped working with 3.12+. More precisely the switch doesnt generate
an acpi event anymore.

Bisecting the kernel showed [0] and [1] as the commits, which
introduced the issue, which is still present in the latest kernel
version.

Looking at the commits it seems this behaviour is somehow intentional,
even if it breaks existing scripts. Except I am missing something I
cant think of any reason to not generate an acpi event for the radio
switch.

Fortunately it's a one liner to reenable the acpi event (see the
attached patch and section [8] at the very bottom of this mail).

[3.] Keywords (i.e., modules, networking, kernel):
[4.] Kernel version (from /proc/version):
Linux version 3.15.0-rc8-custom

[6.] A small shell script or example program which triggers the
     problem (if possible)

acpi_listen -t 10 # and toggle the switch within 10 seconds

Expected output after toggling the switch:
$ acpi_listen -t 10
ibm/hotkey LEN0068:00 00000080 00007000

Actual output is empty.

[7.6.] SCSI information (from /proc/scsi/scsi)
$ cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
  Vendor: ATA      Model: SAMSUNG SSD 830  Rev: CXM0
  Type:   Direct-Access                    ANSI  SCSI revision: 05

[7.7.] Other information that might be relevant to the problem
       (please look in /proc and include all information that you
       think to be relevant):

[8.] Other notes, patches, fixes, workarounds:
The workaround/fix is to allow propagation of the
TP_HKEY_EV_RFKILL_CHANGED event by removing send_acpi_ev = 0 in the
corresponding case-statement.

Thanks for considering this problem report.

Best regards,
Tobias Stegmann
