Patch for Validity Sensors driver
This patch adds support for Validity Sensors proprietary driver. Proprietary driver provides dynamic library libvfsFprintWrapper.so for interaction.
The original patch found in https://github.com/Gnate/libfprint/tree/master/libfprint/drivers/validity
Tested with Validity-Sensor-Setup-4.5-118.00.x86_64. Driver provides support for sensors VFS471, VFS491 and VFS495.
Thanks for your patch, but it won't be merged into libfprint, since it's a wrapper for proprietary library.
Feel free to develop an opensource driver for your device and submit it for review.
