Subject: UBIFS: fix error path in create_default_filesystem()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6dcfb80264be6f83240450428ead88cacadef2cd;p=linux-beck.git

UBIFS: fix error path in create_default_filesystem()

In the end of 'create_default_filesystem()' we need to check
the return value of 'ubifs_write_node()' to ensure that we have
successfully written the 'cs_node'.
