If anyone has any objections, please let me know. ------------------ From: Antoine Tenart [ Upstream commit 4dc5475ae0375ea4f9283dfd9b2ddc91b20d4c4b ] This patch updates the safexcel_hmac_init_pad() function to also wait for completion when the digest return code is -EBUSY, as it would mean the request is in the backlog to be processed later.
