Subject: [PATCH] dm-raid45: API update: Remove dm_put after dm_table_get_md
References: bnc#615656
Patch-mainline: depends on dm-raid45 being upstream
Commit ecdb2e257abc33ae6798d3ccba87bdafa40ef6b6, for 2.6.34, removed
the dm_get() call from dm_table_get_md(). The dm-raid45 code still has
matching dm_put() calls for the dm_table_get_md() calls. This patch removes
the dm_put() calls as it's causing too many reference drops and BUG_ONs.
