Subject: IB/mlx5: Remove dead code from alloc_cached_mr()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d6c7276be180fbd0a30cda8fac5c82d483be47b6;p=linux-beck.git

IB/mlx5: Remove dead code from alloc_cached_mr()

The only place that assigns mr inside the loop already does a break.
So "if (mr)" will never be true here since the function initializes mr
to NULL at the top.  We can just drop the extra if and break here.
