Since the MIPI-DSI interface is stopped at that\npoint, rzg2l_mipi_dsi_host_transfer() triggers the kernel panic.\nFix by moving rzg2l_mipi_dsi_stop() to new callback function\nrzg2l_mipi_dsi_atomic_post_disable().\nWith this change we now have the correct power-down/stop sequence:\nsystemd-shutdown[1]: Rebooting.\nrzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_disable(): entry\nili9881c-dsi 10850000.dsi.0: ili9881c_unprepare(): entry\nrzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_post_disable(): entry\nreboot: Restarting system", "A flaw was found in the Linux kernel's MIPI-DSI driver. When a system with certain display panels is rebooted, the MIPI-DSI interface may stop prematurely. This can lead to a kernel panic, causing the system to crash and resulting in a Denial of Service (DoS)." ],
