[ Upstream commit6b9545dc9f] When reconfiguring CIG after disconnection of the last CIS, LE Remove CIG shall be sent before LE Set CIG Parameters. Otherwise, it fails because CIG is in the inactive state and not configurable (Core v5.3 Vol 6 Part B Sec. 4.5.14.3). This ordering is currently wrong under suitable timing conditions, because LE Remove CIG is sent via the hci_sync queue and may be delayed, but Set CIG Parameters is via hci_send_cmd. Make the ordering well-defined by sending also Set CIG Parameters via hci_sync.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
