[PATCH 07/22] drm/tegra: Remove module ownership from the tegra_fb_ops

2017-05-22 Thread Dmitry Osipenko
The framebuffers console fbcon_startup() increments the tegra_drm module 'use' refcount via try_module_get(), causing an interlock of the DRM subsys and the tegra_drm modules. In result, the tegra_drm module can't be unloaded using rmmod. Signed-off-by: Dmitry Osipenko --- drivers/gpu/drm/tegra/
