From bf6b47deb40f9fc8ddb4573373dc9614aab59d35 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Wed, 11 Apr 2012 23:43:29 +0200 Subject: IB/mlx4: Fix memory leaks in ib_link_query_port() If the call to mlx4_MAD_IFC() fails in ib_link_query_port() we will currently do 'return err;' which will leak 'in_mad' and 'out_mad'. We should instead do 'goto out;' where we'll properly free the memory we previously allocated.
