Hi John,
Commit 04840b50f395 "drivers/platform/x86/sony-laptop.c: fix scancodes"
introduces a gcc warning:
drivers/platform/x86/sony-laptop.c:395:14: warning:
‘scancode’ may be used uninitialized in this function [-Wuninitialized]
Ok, my code was broken, but so was the original - the jogdial device
isn't supposed to send scancodes for it's events:
jog_dev->name = "Sony Vaio Jogdial";
jog_dev->id.bustype = BUS_ISA;
jog_dev->id.vendor = PCI_VENDOR_ID_SONY;
key_dev->dev.parent =&acpi_device->dev;
input_set_capability(jog_dev, EV_KEY, BTN_MIDDLE);
input_set_capability(jog_dev, EV_REL, REL_WHEEL);
Note, no EV_MSC, MSC_SCAN here.
Whoops, anoher bug! Look there, it's setting key_dev->dev.parent
instead of jog_dev.dev_parent!
I'll post a new patch when I've finished testing it.
