commit ad7741ff693a39bab59b75e432bd922a62f3ef0a Author: Hans Petter Selasky <[email protected]> AuthorDate: 2022-05-19 08:06:42 +0000 Commit: Hans Petter Selasky <[email protected]> CommitDate: 2022-05-19 08:13:06 +0000 ibcore: Fix possible memory leak in ib_mad_post_receive_mads() If ib_dma_mapping_error() returns non-zero value, ib_mad_post_receive_mads() will jump out of loops and return -ENOMEM without freeing mad_priv. Fix this memory-leak problem by freeing mad_priv in this case.
