Subject: [PATCH 1/2] workflow: Add workflow files for ci

This patch adds workflow files for ci:

[sync.yml]
 - The workflow file for scheduled work
 - Sync the repo with upstream repo and rebase the workflow branch
 - Review the patches in the patchwork and creates the PR if needed

[ci.yml]
 - The workflow file for CI tasks
 - Run CI tests when PR is created

Subject: [PATCH 2/2] Bluetooth: btintel_pcie: validate completion ring indices

The MSI-X RX and TX completion handlers trust the shared ring indices
read from data->ia.cr_tia[] and data->ia.cr_hia[] before using cr_tia as
an index into the fixed urbd ring arrays. If the device reports a stale
or malformed completion index, the driver can step past rxq->urbd1s[] or
txq->urbd0s[] before it gets a chance to recover.

Validate both completion ring indices against the queue depth before
walking the descriptor arrays.
