[lvm-devel] [PATCH 19/23] Warning - dead code problem elimination

[Zdenek Kabelac]

Original code assign  ret = DM_WAIT_INTR and immediately
reassing this value with result code from dm_task_get_info.

It's not quite clear how such result code is supposed to
fit DM_WAIT defines used in this function (maybe wrong merge?)

Maybe it's actually wrong to assing ret with dm_task_get_info.
So reather then removing line:  ret = DM_WAIT_INTR
patch removes later assignment.

CHECKME!!!
