  "title": "drm: renesas: rz-du: mipi_dsi: fix kernel panic when rebooting for some panels",
  "description": "In the Linux kernel, the following vulnerability has been resolved:  drm: renesas: rz-du: mipi_dsi: fix kernel panic when rebooting for some panels  Since commit 56de5e305d4b (\u0022clk: renesas: r9a07g044: Add MSTOP for RZ/G2L\u0022) we may get the following kernel panic, for some panels, when rebooting:    systemd-shutdown[1]: Rebooting.   Call trace:    ...    do_serror\u002B0x28/0x68    el1h_64_error_handler\u002B0x34/0x50    el1h_64_error\u002B0x6c/0x70    rzg2l_mipi_dsi_host_transfer\u002B0x114/0x458 (P)    mipi_dsi_device_transfer\u002B0x44/0x58    mipi_dsi_dcs_set_display_off_multi\u002B0x9c/0xc4    ili9881c_unprepare\u002B0x38/0x88    drm_panel_unprepare\u002B0xbc/0x108  This happens for panels that need to send MIPI-DSI commands in their unprepare() callback. Since the MIPI-DSI interface is stopped at that point, rzg2l_mipi_dsi_host_transfer() triggers the kernel panic.  Fix by moving rzg2l_mipi_dsi_stop() to new callback function rzg2l_mipi_dsi_atomic_post_disable().  With this change we now have the correct power-down/stop sequence:    systemd-shutdown[1]: Rebooting.   rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_disable(): entry   ili9881c-dsi 10850000.dsi.0: ili9881c_unprepare(): entry   rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_post_disable(): entry   reboot: Restarting system",
