Hi,

Currently when an allocation failure occurs for omap_encoder the exit
path will destroy encoder via omap_encoder_destroy if it is not null.
However, encoder is always null at this point, so the check and destroy
is redundant and can be removed. Clean up the code by removing the exit
path and redundant omap_encoder_destroy call, and just return NULL.

This is correct, but I think it would make sense to fix the error
handling in omap_encoder_init() fully, instead of just partially:
drm_encoder_init() can return an error, in which case we should free the
omap_encoder.
Could you update the patch to do that too?
