commit 5719b81988f3c24ff694dc3a37e35b35630a3966 upstream.

The wireless rfkill should charged by sony-laptop but not acer-wmi.
So, add Sony's SNY5001 acpi device to blacklist in acer-wmi.

Tested on Sony Vaio

Hi Greg,

Please consider this patch for the 3.0, 3.2, and 3.3-stable series.

Without this patch, on affected machines wireless simply doesn't work
unless you unload the acer-wmi driver, regardless of the state of the
physical WIRELESS switch.  "rfkill list" reports sony-wifi unblocked
and acer-wireless soft blocked.  "rfkill unblock 2" has no effect.

Kalle (cc-ed) tried the patch on top of 3.2.y and wifi started working
again on his Sony VAIO VPCYA1V9E.  More details are at

Thanks,
Jonathan
