[PATCH AUTOSEL 5.8 031/101] media: venus: core: Fix error handling in probe

[Sasha Levin <sashal@kernel.org>]

From: Rajendra Nayak <rnayak@codeaurora.org>

[ Upstream commit 98cd831088c64aa8fe7e1d2a8bb94b6faba0462b ]

Post a successful pm_ops->core_get, an error in probe
should exit by doing a pm_ops->core_put which seems
to be missing. So fix it.
