Revision 3cfc183052c3dbf8eae57b6c1685dab00ed3db4a authored by Marek Vasut on 16 October 2021, 21:04:46 UTC, committed by Maarten Lankhorst on 21 October 2021, 09:08:08 UTC
The mxsfb->crtc.funcs may already be NULL when unloading the driver, in which case calling mxsfb_irq_disable() via drm_irq_uninstall() from mxsfb_unload() leads to NULL pointer dereference. Since all we care about is masking the IRQ and mxsfb->base is still valid, just use that to clear and mask the IRQ.
