Description OSIDB Bzimport 2025-12-24 14:06:25 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: rcar_fdp1: Fix refcount leak in probe and remove function

rcar_fcp_get() take reference, which should be balanced with
rcar_fcp_put(). Add missing rcar_fcp_put() in fdp1_remove and
the error paths of fdp1_probe() to fix this.

[hverkuil: resolve merge conflict, remove() is now void]
