**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A refcount leak issue has been identified in the Linux kernel, specifically in the `ill acc of setup()` function related to the MIPS architecture and Ralink setup. The issue arises when `pdev` equals `NULL`, and `of node put(np)` is not called, leading to a resource leak.
**Recommendations**
For the affected Linux kernel versions, ensure that `of node put(np)` is called when `pdev` equals `NULL` in the `ill acc of setup()` function to fix the refcount leak issue.
