Strictly encode patterns of supported hw_variants of firmware files the kernel driver supports requesting. This now includes many missing and previously undeclared module firmware files for 0x07, 0x08, 0x11-0x14, 0x17-0x1b hw_variants.
This especially affects environments that only install firmware files declared and referenced by the kernel modules. In such environments, only the declared firmware files are copied resulting in most Intel Bluetooth devices not working. I.e. host-only dracut-install initrds, or Ubuntu Core kernel snaps.
BugLink: https://bugs.launchpad.net/bugs/1970819 Cc: stable@vger.kernel.org # 4.15+ Signed-off-by: Dimitri John Ledkov dimitri.ledkov@canonical.com
Notes: Changes since v4: - Add missing "intel/" prefix for 0x17+ firmware - Add Cc stable for v4.15+ kernels Changes since v3: - Hopefully pacify trailing whitespace from GitLint in this optional portion of the commit. Changes since v2: - encode patterns for 0x17 0x18 0x19 0x1b hw_variants - rebase on top of latest rc tag Changes since v1: - encode strict patterns of supported firmware files for each of the supported hw_variant generations.
