2023-10-11drm/etnaviv: Replace strncpy with strscpy_padJustin Stitt
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We should prefer more robust and less ambiguous string interfaces. A suitable replacement is `strscpy_pad` due to the fact that it guarantees NUL-termination on the destination buffer whilst maintaining the NUL-padding behavior that strncpy provides.

2023-10-10drm/panel: boe-tv101wum-nl6: Completely pull GPW to VGL before TP termRuihai Zhou
The sta_himax83102 panel sometimes shows abnormally flickering horizontal lines. The front gate output will precharge the X point of the next pole circuit before TP(TouchPanel Enable) term starts, and wait until the end of the TP term to resume the CLK. For this reason, the X point must be maintained during the TP term. In abnormal case, we measured a slight leakage at point X. This because during the TP term, the GPW does not fully pull the VGL low, causing the TFT to not be closed tightly. To fix this, we completely pull GPW to VGL before entering the TP term. This will ensure that the TFT is closed tightly and prevent the abnormal display.
