[PATCH 5.4 01/90] crypto: ccp - Release all allocated memory if sha type is invalid

[Greg Kroah-Hartman]

From: Navid Emamdoost <navid.emamdoost@xxxxxxxxx>

[ Upstream commit 128c66429247add5128c03dc1e144ca56f05a4e2 ]

Release all allocated memory if sha type is invalid:
In ccp_run_sha_cmd, if the type of sha is invalid, the allocated
hmac_buf should be released.

v2: fix the goto.
