ubifs: Add separate functions to init/crc a node
When adding authentication support we will embed a HMAC into some nodes. To prepare these nodes we have to first initialize the nodes, then add a HMAC and finally add a CRC. To accomplish this add separate ubifs_init_node/ubifs_crc_node functions. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Richard Weinberger <richard@nod.at>
