Subject: [PATCH] drm/vc4: clean up error exit path on failed dpi_connector
|
|
allocation
|
|
|
|
There is redundant code in the clean up exit path when dpi_connector
|
|
fails to be allocated. The current code checks if connector is NULL
|
|
before destroying it, in fact, connector is NULL at this point so
|
|
the check is redundant and can be removed. The final clean up is
|
|
that we can remove the goto fail with a simple return and the unused
|
|
variable ret.
