[PATCH AUTOSEL 6.6 2/4] cdrom: rearrange last_media_change check to avoid unintentional overflow

[Sasha Levin]

From: Justin Stitt <justinstitt@google.com>

[ Upstream commit efb905aeb44b0e99c0e6b07865b1885ae0471ebf ]

When running syzkaller with the newly reintroduced signed integer wrap
sanitizer we encounter this splat:

Historically, the signed integer overflow sanitizer did not work in the
kernel due to its interaction with `-fwrapv` but this has since been
changed [1] in the newest version of Clang. It was re-enabled in the
kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow
sanitizer").

Let's rearrange the check to not perform any arithmetic, thus not
tripping the sanitizer.

[PATCH AUTOSEL 6.6 3/4] ALSA: hda/realtek: Enable headset mic of JP-IK LEAP W502 with ALC897

From: Jian-Hong Pan <jhp@endlessos.org>

[ Upstream commit 45e37f9ce28d248470bab4376df2687a215d1b22 ]

JP-IK LEAP W502 laptop's headset mic is not enabled until
ALC897_FIXUP_HEADSET_MIC_PIN3 quirk is applied.

[PATCH AUTOSEL 6.6 4/4] vhost-scsi: Handle vhost_vq_work_queue failures for events

[Sasha Levin]

From: Mike Christie <michael.christie@oracle.com>

[ Upstream commit b1b2ce58ed23c5d56e0ab299a5271ac01f95b75c ]

Currently, we can try to queue an event's work before the vhost_task is
created. When this happens we just drop it in vhost_scsi_do_plug before
even calling vhost_vq_work_queue. During a device shutdown we do the
same thing after vhost_scsi_clear_endpoint has cleared the backends.

In the next patches we will be able to kill the vhost_task before we
have cleared the endpoint. In that case, vhost_vq_work_queue can fail
and we will leak the event's memory. This has handle the failure by
just freeing the event. This is safe to do, because
vhost_vq_work_queue will only return failure for us when the vhost_task
is killed and so userspace will not be able to handle events if we
sent them.
