[SRU][Bionic][PATCH 0/1] s390/zcrypt: Fix CCA and EP11 CPRB processing failure memory leak.

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1775390

== SRU Justification ==
Description: kernel: Fix memory leak on CCA and EP11 CPRB processing.

Symptom: Kernel memory not freed when CCA or EP11 CPRB processing fails.
Problem: kfree() in code error path missing.

Solution: Slight rework of the malloc and free places.

Reproduction: Run application which sends CCA or EP11 crypto requests
              to the crypto card(s). Now switch the cards offline with
              the help of chzcrypt. Monitor top or free output.

== Fix ==
89a0c0ec0d2e ("s390/zcrypt: Fix CCA and EP11 CPRB processing failure memory leak.")

== Regression Potential ==
Low.  Limited to s390.

== Test Case ==
Verified upfront by IBM during upstream integration.
