[dm-devel] [PATCH] dm-log: fix return value in create_log_context function

[Takahiro Yasui <tyasui redhat com>]

Hi,

This is very trivial fix, but let me post it to improve code
readability. In the current implementation, caller function
does not use the return value and no action is changed.

Regards,

When dm_io_client_create function fails in create_log_context
function, return value is set to variable r but it is not used.
r should be returned.
