sony-laptop: SPIC unset IRQF_SHARED, set IRQF_DISABLED
The SPIC irq is not really shareable, the IO port cannot be cleared and always returns some data so there is no real way to understand if the irq is for us or not. Moreover the _PRS acpi method says the irq is not shareable. In addition to this, in some cases, an additional write to the IO port has to be performed in order to properly decode the event received from the device. This generates another interrupt which may overlap with the previous one. In the future this is going to be important for properly decoding events.
