patch #1 is code refactorings to use devm_drm_dev_alloc.
patch #2 add the new api to install irq, patch #3 is hibmc driver uses
the newly added api to register interrupts.
Tian Tao (3):
drm/hisilicon: Code refactoring for hibmc_drm_drv
drm/irq: Add the new api to install irq
drm/hisilicon: Use the new api devm_drm_irq_install
