Nicolas Saenz Julienne 60831f5ae6 firmware: raspberrypi: Keep count of all consumers ... [ Upstream commit 1e7c57355a ] When unbinding the firmware device we need to make sure it has no consumers left. Otherwise we'd leave them with a firmware handle pointing at freed memory. Keep a reference count of all consumers and introduce rpi_firmware_put() which will permit automatically decrease the reference count upon unbinding consumer drivers.
