[PATCH 07/10] drm/qxl: Move ioctl array next to its only user

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

Move the array qxl_ioctl to qxl_drv.c and initialize the num_ioctls
field of struct drm_driver at runtime. Replaces the current fragile
ioctl setup and allows for generating the module init/exit code.
