Description
In the Linux kernel, the following vulnerability has been resolved: media: venus: core: Fix some resource leaks in the error path of 'venus_probe()' If an error occurs after a successful 'of_icc_get()' call, it must be undone. Use 'devm_of_icc_get()' instead of 'of_icc_get()' to avoid the leak. Update the remove function accordingly and axe the now unneeded 'icc_put()' calls.
