[PATCH 0/2] drm: Add a check to prevent NULL pointer dereference

drm_mode_duplicate() could return NULL due to lack of memory, which could cause NULL pointer dereference. Add a check to prevent it. Zhang Zekun (2): drm/i2c/ch7006: Add a check to prevent NULL pointer dereference drm/panel: himax-hx83102: Add a check to prevent NULL pointer dereference

[PATCH 2/2] drm/panel: himax-hx83102: Add a check to prevent NULL pointer dereference
