nvec_msg_free: : A &struct nvec_chip : A message (must be allocated by nvec_msg_alloc() and belong to )
Free the given message

nvec_register_notifier - Register a notifier with nvec : A &struct nvec_chip : The notifier block to register
Registers a notifier with . The notifier will be added to an atomic notifier chain that is called for all received messages except those that correspond to a request initiated by nvec_write_sync().
Definition at line 114 of file nvec.c.
nvec_write_async - Asynchronously write a message to NVEC : An nvec_chip instance : The message data, starting with the request type : The size of
Queue a single message to be transferred to the embedded controller and return immediately.
Returns: 0 on success, a negative error code on failure. If a failure occured, the nvec driver may print an error.
Definition at line 248 of file nvec.c.
nvec_write_sync - Write a message to nvec and read the response : An &struct nvec_chip : The data to write : The size of
This is similar to nvec_write_async(), but waits for the request to be answered before returning. This function uses a mutex and can thus not be called from e.g. interrupt handlers.
Returns: A pointer to the response message on success, NULL on failure. Free with nvec_msg_free() once no longer used.
