Descriptions

In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: check for valid hw_pp in dpu_encoder_helper_phys_cleanup The commit 8b45a26f2ba9 ("drm/msm/dpu: reserve cdm blocks for writeback
in case of YUV output") introduced a smatch warning about another
conditional block in dpu_encoder_helper_phys_cleanup() which had assumed
hw_pp will always be valid which may not necessarily be true. Lets fix the other conditional block by making sure hw_pp is valid
before dereferencing it. Patchwork: https://patchwork.freedesktop.org/patch/574878/

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/msm/dpu: check for valid hw_pp en dpu_encoder_helper_phys_cleanup. El commit 8b45a26f2ba9 ("drm/msm/dpu: reserve bloques cdm para reescritura en caso de salida YUV") introdujo una coincidencia advertencia sobre otro bloque condicional en dpu_encoder_helper_phys_cleanup() que había asumido que hw_pp siempre será válido, lo que puede no ser necesariamente cierto. Arreglemos el otro bloque condicional asegurándonos de que hw_pp sea válido antes de eliminar la referencia a él. Remiendo: https://patchwork.freedesktop.org/patch/574878/
