Quanyang Wang c533cf50fd ubifs: Fix memory leak from c->sup_node ... commit ff90bdfb20 upstream. The c->sup_node is allocated in function ubifs_read_sb_node but is not freed. This will cause memory leak as below: unreferenced object 0xbc9ce000 (size 4096): comm "mount", pid 500, jiffies 4294952946 (age 315.820s) hex dump (first 32 bytes): 31 18 10 06 06 7b f1 11 02 00 00 00 00 00 00 00 1....{.......... 00 10 00 00 06 00 00 00 00 00 00 00 08 00 00 00 ................ backtrace: [<d1c503cd>] ubifs_read_superblock+0x48/0xebc [<a20e14bd>] ubifs_mount+0x974/0x1420 [<8589ecc3>] legacy_get_tree+0x2c/0x50 [<5f1fb889>] vfs_get_tree+0x28/0xfc [<bbfc7939>] do_mount+0x4f8/0x748 [<4151f538>] ksys_mount+0x78/0xa0 [<d59910a9>] ret_fast_syscall+0x0/0x54 [<1cc40005>] 0x7ea02790 Free it in ubifs_umount and in the error path of mount_ubifs.
