[PATCH 0/7] gpu: drm: remaining missing of_node_put issue fixes

[Peter Chen]

Hi David,

This is remaining missing of_node_put issue fix for gpu/drm drivers, the
other fixes I sent yesterday. I think it may be easier for reviewing
using patch set for similar issue, thanks.

Peter Chen (7):
  gpu: drm: rockchip_drm_drv: add missing of_node_put after calling
    of_parse_phandle
  gpu: drm: sti_compositor: add missing of_node_put after calling
    of_parse_phandle
  gpu: drm: sti_vdo: add missing of_node_put after calling
    of_parse_phandle
  gpu: drm: sti_hqvdp: add missing of_node_put after calling
    of_parse_phandle
  gpu: drm: sti_vtg: add missing of_node_put after calling
    of_parse_phandle
  gpu: drm: sun4i_drv: add missing of_node_put after calling
    of_parse_phandle
  gpu: drm: vc4_hdmi: add missing of_node_put after calling
    of_parse_phandle

It would be nice if we could just pass the phandle spec directly to the
i2c function.  OF code always seems terribly verbose to me (and
error-prone in this exact way) because of the separate phandle lookup.

Yeah, of_find_i2c_adapter_by_phandle would be neat. Either way, applied
all the other patches to drm-misc.
