If anyone has any objections, please let me know. ------------------ From: Yichong Chen [ Upstream commit ce12a39bed483008683438962b3a605374e6f803 ] exfat_alloc_new_dir() allocates a cluster for a new directory before zeroing it. If exfat_zeroed_cluster() fails, the function returns the error but leaves the allocated cluster in use. Free the newly allocated cluster before returning the zeroing error.
