[PATCH v3 2/3] NFC: nci: export nci_core_reset and nci_core_init

From: Robert Baldyga
Date: Thu Aug 20 2015 - 11:27:03 EST


Some drivers needs to have ability to reinit NCI core, for example after
updating firmware in setup() of post_setup() callback. This patch makes
nci_core_reset() and nci_core_init() functions public, to make it possible.
