commit205608749eupstream. Since v5.4-rc1 was released, iwlwifi started throwing errors when scan commands were sent to the firmware with certain devices (depending on the OTP burned in the device, which contains the list of available channels). For instance: iwlwifi 0000:00:14.3: FW error in SYNC CMD SCAN_CFG_CMD This bug was reported in the ArchLinux bug tracker: https://bugs.archlinux.org/task/64703 And also in a specific case in bugzilla, when the lar_disabled option was set: https://bugzilla.kernel.org/show_bug.cgi?id=205193 Revert the commit that introduced this error, by using the number of channels from the OTP instead of the number of channels that is specified in the FW TLV that tells us how many channels it supports. This reverts commit06eb547c4a.

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.
