Later this adjusted address might be used for memory dumping.\nHowever the size that is used for memory dumping isn't adjusted to\naccount for the io_offset, leading to the potential access to the\nunmapped region. Lower ctrl_size by the io_offset value to prevent\naccess past the mapped area.\n\n msm_disp_snapshot_add_block+0x1d4/0x3c8 [msm] (P)\n msm_dsi_host_snapshot+0x4c/0x78 [msm]\n msm_dsi_snapshot+0x28/0x50 [msm]\n msm_disp_snapshot_capture_state+0x74/0x140 [msm]\n msm_disp_snapshot_state_sync+0x60/0x90 [msm]\n _msm_disp_snapshot_work+0x30/0x90 [msm]\n kthread_worker_fn+0xdc/0x460\n kthread+0x120/0x140\n\nPatchwork: https://patchwork.freedesktop.org/patch/721747/",
