Subject: [PATCH 5.11 571/775] scsi: sd: Fix Opal support

From: Bart Van Assche <bvanassche@....org>

commit aaf15f8c6de932861f1fce6aeec6a89ac0e354b6 upstream.

The SCSI core has been modified recently such that it only processes PM
requests if rpm_status != RPM_ACTIVE. Since some Opal requests are
submitted while rpm_status != RPM_ACTIVE, set flag RQF_PM for Opal
requests.

See also https://bugzilla.kernel.org/show_bug.cgi?id=211227.

[mkp: updated sha for PM patch]

Link: https://lore.kernel.org/r/20210222021042.3534-1-bvanassche@acm.org
Fixes: d80210f25ff0 ("sd: add support for TCG OPAL self encrypting disks")
Fixes: e6044f714b25 ("scsi: core: Only process PM requests if rpm_status != RPM_ACTIVE")
