From ba391e5a5ac6697b8bcae8c0d01439cb765d9ef8 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Wed, 21 May 2014 11:15:56 -0400 Subject: HID: rmi: do not handle touchscreens through hid-rmi Currently, hid-rmi drives every Synaptics product, but the touchscreens on the Windows tablets should be handled through hid-multitouch. Instead of providing a long list of PIDs, rely on the scan_report capability to detect which should go to hid-multitouch, and which should not go to hid-rmi. related bug: https://bugzilla.kernel.org/show_bug.cgi?id=74241 https://bugzilla.redhat.com/show_bug.cgi?id=1089583 Signed-off-by: Benjamin Tissoires Signed-off-by: Jiri Kosina --- drivers/hid/hid-core.c | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-) (limited to 'drivers/hid/hid-core.c') diff --git a/drivers/hid/hid-core.c b/drivers/hid/hid-core.c index f05255d92de7..64c71c866916 100644 --- a/drivers/hid/hid-core.c +++ b/drivers/hid/hid-core.c @@ -776,6 +776,14 @@ static int hid_scan_report(struct hid_device *hid) (hid->group == HID_GROUP_MULTITOUCH)) hid->group = HID_GROUP_MULTITOUCH_WIN_8; + /* + * Vendor specific handlings + */ + if ((hid->vendor == USB_VENDOR_ID_SYNAPTICS) && + (hid->group == HID_GROUP_GENERIC)) + /* hid-rmi should take care of them, not hid-generic */ + hid->group = HID_GROUP_RMI; + vfree(parser); return 0; } @@ -1882,8 +1890,6 @@ static const struct hid_device_id hid_have_special_driver[] = { { HID_USB_DEVICE(USB_VENDOR_ID_SONY, USB_DEVICE_ID_SONY_VAIO_VGP_MOUSE) }, { HID_USB_DEVICE(USB_VENDOR_ID_STEELSERIES, USB_DEVICE_ID_STEELSERIES_SRWS1) }, { HID_USB_DEVICE(USB_VENDOR_ID_SUNPLUS, USB_DEVICE_ID_SUNPLUS_WDESKTOP) }, - { HID_USB_DEVICE(USB_VENDOR_ID_SYNAPTICS, HID_ANY_ID) }, - { HID_I2C_DEVICE(USB_VENDOR_ID_SYNAPTICS, HID_ANY_ID) }, { HID_USB_DEVICE(USB_VENDOR_ID_THINGM, USB_DEVICE_ID_BLINK1) }, { HID_USB_DEVICE(USB_VENDOR_ID_THRUSTMASTER, 0xb300) }, { HID_USB_DEVICE(USB_VENDOR_ID_THRUSTMASTER, 0xb304) }, -- cgit v1.2.1
