Subject: dm space map metadata: fix sm_bootstrap_get_nr_blocks()
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit c1c6156fe4d4577444b769d7edd5dd503e57bbc9 upstream.
This function isn't right and it causes a static checker warning:
drivers/md/dm-thin.c:3016 maybe_resize_data_dev()
error: potentially using uninitialized 'sb_data_size'.
It should set "*count" and return zero on success the same as the
sm_metadata_get_nr_blocks() function does earlier.
Fixes: 3241b1d3e0aa ('dm: add persistent data library')
