Some devices come with weird values in their device descriptors and this quirk enables their initialization even if the logical minimum of the DEVICE_CONTROL page is not 1. Fixes initialization of VRS Direct Force Pro Changes in v6: - Change quirk name to better reflect it's intention Co-developed-by: Makarenko Oleg Signed-off-by: Makarenko Oleg Signed-off-by: Tomasz Pakuła Reviewed-by: Michał Kopeć Reviewed-by: Paul Dino Jones Tested-by: Paul Dino Jones Tested-by: Cristóferson Bueno Tested-by: Pablo Cisneros Signed-off-by: Jiri Kosina Signed-off-by: Sasha Levin --- diff --git a/drivers/hid/usbhid/hid-pidff.c b/drivers/hid/usbhid/hid-pidff.c index 503b22feacdbb..5a57ba0d7026a 100644 --- a/drivers/hid/usbhid/hid-pidff.c +++ b/drivers/hid/usbhid/hid-pidff.c @@ -969,7 +969,8 @@ static int pidff_find_special_fields(struct pidff_device *pidff) 0x57, 0); pidff->device_control = pidff_find_special_field(pidff->reports[PID_DEVICE_CONTROL], - 0x96, 1); + 0x96, !(pidff->quirks & HID_PIDFF_QUIRK_PERMISSIVE_CONTROL)); + pidff->block_load_status = pidff_find_special_field(pidff->reports[PID_BLOCK_LOAD], 0x8b, 1); diff --git a/include/linux/hid.h b/include/linux/hid.h index 8876d5f0cd87f..a06f38c1441ad 100644 --- a/include/linux/hid.h +++ b/include/linux/hid.h @@ -1219,8 +1219,9 @@ int hid_pidff_init(struct hid_device *hid); #endif /* HID PIDFF quirks */ -#define HID_PIDFF_QUIRK_MISSING_DELAY BIT(0) -#define HID_PIDFF_QUIRK_MISSING_PBO BIT(1) +#define HID_PIDFF_QUIRK_MISSING_DELAY BIT(0) +#define HID_PIDFF_QUIRK_MISSING_PBO BIT(1) +#define HID_PIDFF_QUIRK_PERMISSIVE_CONTROL BIT(2) #define dbg_hid(fmt, ...) pr_debug("%s: " fmt, __FILE__, ##__VA_ARGS__)
