"value": "In the Linux kernel, the following vulnerability has been resolved:\n\ndrm: renesas: rz-du: mipi_dsi: fix kernel panic when rebooting for some panels\n\nSince commit 56de5e305d4b (\"clk: renesas: r9a07g044: Add MSTOP for RZ/G2L\")\nwe may get the following kernel panic, for some panels, when rebooting:\n\n systemd-shutdown[1]: Rebooting.\n Call trace:\n ...\n do_serror+0x28/0x68\n el1h_64_error_handler+0x34/0x50\n el1h_64_error+0x6c/0x70\n rzg2l_mipi_dsi_host_transfer+0x114/0x458 (P)\n mipi_dsi_device_transfer+0x44/0x58\n mipi_dsi_dcs_set_display_off_multi+0x9c/0xc4\n ili9881c_unprepare+0x38/0x88\n drm_panel_unprepare+0xbc/0x108\n\nThis happens for panels that need to send MIPI-DSI commands in their\nunprepare() callback. Since the MIPI-DSI interface is stopped at that\npoint, rzg2l_mipi_dsi_host_transfer() triggers the kernel panic.\n\nFix by moving rzg2l_mipi_dsi_stop() to new callback function\nrzg2l_mipi_dsi_atomic_post_disable().\n\nWith this change we now have the correct power-down/stop sequence:\n\n systemd-shutdown[1]: Rebooting.\n rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_disable(): entry\n ili9881c-dsi 10850000.dsi.0: ili9881c_unprepare(): entry\n rzg2l-mipi-dsi 10850000.dsi: rzg2l_mipi_dsi_atomic_post_disable(): entry\n reboot: Restarting system"
