This reverts commit cc195141. This commit was problematic on other OSes. The real solution is to leave all the error checking to DRM and don't do it in DC, which is addressed by "Return aux replies directly to DRM" later in this patchset. v2: Add reason for revert. Signed-off-by:

We are initializing the entity before the scheduler is actually initialized. This can lead to all kind of problem, but especially NULL pointer deref because of Nayan's scheduler work. Signed-off-by:

A call to ttm_bo_unref() clears the supplied pointer to NULL, while ttm_bo_put() does not. None of the converted call sites requires the pointer to become NULL, so the respective assign operations has been left out from the patch. Signed-off-by:

Thomas Zimmermann authored
The TTM buffer-object interface provides ttm_bo_reference() and ttm_bo_unref() for managing reference counts. Replacing them with ttm_bo_get() and ttm_bo_put() aligns the API with conventions used throughout the Linux kernel. The implementation of ttm_bo_unref() clears the supplied pointer to NULL. This leads to workarounds where the caller saves the pointer's value before de-referencing the BO. ttm_bo_put() does not clear the supplied pointer. Signed-off-by:
