Subject: [PATCH 5.16 0278/1039] crypto: hisilicon/qm - fix incorrect return value of hisi_qm_resume()

From: Weili Qian <qianweili@...wei.com>

[ Upstream commit 3f9dd4c802b96626e869b2d29c8e401dabadd23e ]

When hisi_qm_resume() returns 0, it indicates that the device has started
successfully.  If the device fails to start, hisi_qm_resume() needs to
return the actual error code to the caller instead of 0.
