Subject: [PATCH] drm/vc4: hvs: Print error if we fail an allocation
|
|
|
|
We need to allocate a few additional structures when checking our
|
|
atomic_state, especially related to hardware SRAM that will hold the
|
|
plane descriptors (DLIST) and the current line context (LBM) during
|
|
composition.
|
|
|
|
Since those allocation can fail, let's add some error message in that
|
|
case to help debug what goes wrong.
