qdev->monitors_config->max_allowed is effectively set by the qxl.num_heads module parameter, stored in the qxl_num_crtc variable. Lets get rid of the indirection and use the variable qxl_num_crtc directly. The kernel doesn't need to dereference pointers each time it needs the value, and when reading the code you don't have to trace where and why

Move final cleanups to qxl_drm_release() callback. Add drm_atomic_helper_shutdown() call to qxl_pci_remove().

If qxl_alloc_client_monitors_config() fails to allocate client_monitors_config then NULL pointer dereference occurs in function qxl_display_copy_rom_client_monitors_config() after qxl_alloc_client_monitors_config() call. The patch adds return error from qxl_alloc_client_monitors_config() and additional status for qxl_display_copy_rom_client_monitors_config return value. Found by Linux Driver

When reading the monitor config fails, don't retry forever. If it fails ten times in a row just give up to avoid the driver hangs. Also add a small delay after each attempt, so the host has a chance to complete a partial update.

Try to read the client monitors config at driver load time, even without explicit notification. So in case that info was filled before the driver loaded and we've missed the notifications because of that the settings will still be used. With that place we now have to take care to properly handle a empty client monitors config, so we don't trip over an uninitialized client monitors
