Subject[PATCH 5.3 116/344] media: vsp1: fix memory leak of dl on error return path
Date
From: Colin Ian King <colin.king@canonical.com>

[ Upstream commit 70c55c1ad1a76e804ee5330e134674f5d2741cb7 ]

Currently when the call vsp1_dl_body_get fails and returns null the
error return path leaks the allocation of dl. Fix this by kfree'ing
dl before returning.

Addresses-Coverity: ("Resource leak")

Fixes: 5d7936b8e27d ("media: vsp1: Convert display lists to use new body pool")
