Applied to u-boot-ubi/master after minor coding style fix (line over 80 chars).

Using ZLIB compression with UBIFS fails if last data node is not a size of UBIFS_BLOCK_SIZE (4096 bytes). Easiest way to test this is trying to read a file smaller than 4k: => ubifsload 41000000 /etc/fstab Loading file '/etc/fstab' to addr 0x41000000 with size 704 (0x000002c0)... UBIFS error (pid 0): read_block: bad data node (block 0, inode 2506) UBIFS error (pid 0): do_readpage: cannot read page 0 of inode 2506, error -22 Error reading file '/etc/fstab' /etc/fstab not found! exit not allowed from main input shell. => With this patch: => ubifsload 41000000 /etc/fstab Loading file '/etc/fstab' to addr 0x41000000 with size 704 (0x000002c0)...
