FROMGIT: scsi: ufs: Complete pending requests in host reset and restore path In UFS host reset and restore path, before probe, we stop and start the host controller once. After host controller is stopped, the pending requests, if any, are cleared from the doorbell, but no completion IRQ would be raised due to the hba is stopped. These pending requests shall be completed along with the first NOP_OUT command (as it is the first command which can raise a transfer completion IRQ) sent during probe. Since the OCSs of these pending requests are not SUCCESS (because they are not yet literally finished), their UPIUs shall be dumped. When there are multiple pending requests, the UPIU dump can be overwhelming and may lead to stability issues because it is in atomic context. Therefore, before probe, complete these pending requests right after host controller is stopped and silence the UPIU dump from them.
