    Subject[PATCH v2 00/37] drm: Make drivers to honour the nomodeset parameter
    Date
    The nomodeset kernel command line parameter is used to prevent the KMS/DRM
    drivers to be registered/probed. But only a few drivers implement support
    for this and most DRM drivers just ignore it.

    This patch series is a v2 to make DRM drivers to honour nomodeset. It is
    posted as separate patches to make easier for drivers maintainers to ack
    or pick them independently at their own pace.

    The drm_module_{pci,platform}_driver() helper macros are added, which are
    just wrappers around module_{pci,platform}_driver() but adding a check for
    drm_firmware_drivers_only() and returning -ENODEV if that is true.

    PCI and platform DRM drivers are then modified in the following patches to
    make use of those macros.

    For drivers that have custom module init/exit, the check is added to these
    functions instead. Since the drm_*_module_driver() macros are only for the
    default case when the init/exit just register/unregister the driver type.

    In v1 all KMS/DRM drivers were included but v2 only includes KMS drivers,
    and only the the PCI and platform DRM drivers. A follow-up series might
    do the same for rendering-only and USB/SPI/I2C drivers, but it will need
    more discussion to agree if that's desirable.

    I've built tested with 'make allmodconfig && make M=drivers/gpu/drm' but I
    don't have hardware to test the drivers, so review/testing is appreciated.

    Best regards,
    Javier

    Changes in v2:
    - Add drm_module_{pci,platform}_driver() macros and put the check there
    (Thomas Zimmermann).
    - Use the drm_module_*_driver() macros if possible (Thomas Zimmermann).
    - Leave the DRM drivers that don't set the DRIVER_MODESET driver feature
    (Lucas Stach).
    - Leave USB/SPI/I2C drivers and only include PCI and platform ones
    (Noralf Trønnes).
    - Add collected Reviewed-by tags
