Subject: [PATCH 0/6] drm/tegra: Fix some error handling paths

Most of the patches are retated to tegra_output_probe() and missing
tegra_output_remove(). Others are things spotted while writting the serie.


Patches 1, 3, 4 are verbose, but some functions called in the probe can
return -EPROBE_DEFER, so it is nice to correctly release resources.

Maybe moving the tegra_output_probe() call would minimize the changes, but I'm
always reluctant to move code, because of possible side-effects.


Christophe JAILLET (6):
  drm/tegra: dsi: Fix some error handling paths in tegra_dsi_probe()
  drm/tegra: dsi: Fix missing pm_runtime_disable() in the error handling
    path of tegra_dsi_probe()
  drm/tegra: dsi: Fix some error handling paths in tegra_hdmi_probe()
  drm/tegra: rgb: Fix some error handling paths in tegra_dc_rgb_probe()
  drm/tegra: rgb: Fix missing clk_put() in the error handling paths of
    tegra_dc_rgb_probe()
  drm/tegra: output: Fix missing i2c_put_adapter() in the error handling
    paths of tegra_output_probe()
