First memleak is found by mounting corrupted UBIFS image with chk_index
enabled.
Second memleak is found by powercut testing for encryption scenario.

v1->v2:
 ubifs_symlink: Call fscrypt_free_inode() directly in error handling path.
 Add 'Cc: stable@vger.kernel.org' and 'Suggested-by' tags in patch 2.
v2->v3:
 Handle tnc releasing in error handling path in dbg_check_idx_size().


Zhihao Cheng (2):
  ubifs: dbg_check_idx_size: Fix kmemleak if loading znode failed
  ubifs: ubifs_symlink: Fix memleak of inode->i_link in error path
