If anyone has any objections, please let me know. ------------------ From: Zhang Yi [ Upstream commit 7f174ae4f39e8475adcc09d26c5a43394689ad6c ] Now that the calculation of fastmap size in ubi_calc_fm_size() is incorrect since it miss each user volume's ubi_fm_eba structure and the Internal UBI volume info. Let's correct the calculation.
