jffs2: Fix return value from jffs2_do_readpage_nolock()
This fixes "kernel BUG at fs/jffs2/file.c:251!". This pseudocode hopefully illustrates the scenario that triggers it: jffs2_write_begin { jffs2_do_readpage_nolock { jffs2_read_inode_range { jffs2_read_dnode { Data CRC 33c102e9 != calculated CRC 0ef77e7b for node at 005d42e4 return -EIO; } } ClearPageUptodate(pg); return 0; } } jffs2_write_end { BUG_ON(!PageUptodate(pg)); } Signed-off-by: Anders Grafström <grfstrm@users.sourceforge.net> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
