- * FpSdcpDeviceClass:
- * @connect: Establish SDCP connection. Similar to open in #FpDeviceClass
- *   but called connect to mirror the SDCP specification.
- * @reconnect: Perform a faster reconnect. Drivers do not need to provide this
- *   function. If reconnect fails, then a normal connect will be tried.
- * @enroll_begin: Start the enrollment procedure. In the absence of an error,
- *   the driver must call fpi_sdcp_device_enroll_set_nonce() at any point. It
- *   also must report enrollment progress using fpi_device_enroll_progress().
- *   It should also store available metadata about the print in device memory.
- *   The operation is completed with fpi_sdcp_device_enroll_ready().
- * @enroll_commit: Complete the enrollment procedure. This commits the newly
- *   enrolled print to the device memory. Will only be called if enroll_begin
- *   succeeded. The passed id may be %NULL, in that case the driver must
- *   abort the enrollment process. id is owned by the base class and remains
- *   valid throughout the operation.
- * @identify: Start identification process. On completion, the driver must call
- *   fpi_sdcp_device_identify_complete(). To request the user to retry the
- *   fpi_sdcp_device_identify_retry() function is used.
- *
- *
- * These are the main entry points for drivers implementing SDCP.
- *
- * Drivers *must* eventually call the corresponding function to finish the
- * operation.
- *
- * XXX: Is the use of fpi_device_action_error() acceptable?
- *
- * Drivers *must* also handle cancellation properly for any long running
- * operation (i.e. any operation that requires capturing). It is entirely fine
- * to ignore cancellation requests for short operations (e.g. open/close).
- *
- * This API is solely intended for drivers. It is purely internal and neither

Matthew Mirvish	46591d7bfa	elanspi: preliminary support for 04f3:3104 Also adds "quirk" flags to driver_data so other special case things can be handled with less effort going forwards.	2022-05-03 21:02:26 -04:00

Benjamin Berg	da1a56a600	context: Log version number at startup Having this should at least give us a slightly better idea about the version that the user has installed. Obviously it is still not very accurate (maybe a git hash would be good if available?), but it should still be helpful overall.	2022-04-10 13:58:58 +02:00

Benjamin Berg	5fb3b8b43a	tests: Avoid -Wdangling-pointer warning The code is correct, but gcc thinks the pointer is still NULL after the call. As obvious workaround don't seem to work, just disable the warning for now.	2022-02-14 17:57:59 +01:00
