Subject: media: coda: Fix missing put_device() call in coda_get_vdoa_data
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c7bc9395aeb08d4bb5caccc580929e33f5d997d2;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

media: coda: Fix missing put_device() call in coda_get_vdoa_data

[ Upstream commit ca85d271531a1e1c86f24b892f57b7d0a3ddb5a6 ]

The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore.
Add the corresponding 'put_device()' in the error handling path.
