This patch series fixes a regression that was introduced by one of the changes I made to when Tegra registers its AUX adapters, along with fixing some reference leaks that I found along the way. !!!NOTE!!! There's one thing I'm not entirely sure about, which is the use of module references (e.g. try_module_get()) here. If I'm understanding how this code worked previously: since the get_device call in tegra_sor_probe() was previously the i2c adapter for the AUX channel - which itself is initialized in drm_dp_aux_register() - then I -think- that the module owner for the DDC adapter would likely have been drm_kms_helper. With these changes, if I'm understanding things correctly we're now just grabbing a module reference for ourselves - something which might not be the best idea? If anyone could confirm if I need to fix this or not that'd be appreciated, along with reviews of course :P Lyude Paul (2): drm/tegra: Get ref for DP AUX channel, not its ddc adapter drm/tegra: Fix DP AUX channel reference leaks drivers/gpu/drm/tegra/sor.c | 25 ++++++++++++++++++------- 1 file changed, 18 insertions(+), 7 deletions(-) -- 2.30.2
