This is a single-patch fix for the `panel-himax-hx83102` driver. The bug is straightforward: `hx83102_disable()` clears `MIPI_DSI_MODE_LPM` to send the display-off and enter-sleep-mode commands in HS (high-speed) mode, but never restores the flag afterward. When the panel is later re-prepared, the init sequence runs without `MIPI_DSI_MODE_LPM`, causing the prepare to fail and breaking screen unblanking.
The fix is correct and follows the exact same pattern already used by `hx83102_bl_update_status()` and `hx83102_bl_get_brightness()` in the same file — clear LPM before the commands, restore it after.
**Verdict: Looks good.** This is a clean, minimal bug fix suitable for stable backport.
