Subject[PATCH -next] tpm: change the return type of calc_tpm2_event_size to size_t
Date
calc_tpm2_event_size return size of the event which type is
size_t, If it is an invalid event, returns 0. And all the
caller use a size_t variable to check the return value, so
no need to convert to the return value type to int.
