And use devm_platform_get_and_ioremap_resource() to simplify code. The Linux kernel CVE team has assigned CVE-2022-49435 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/mfd/davinci_voicecodec.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/49c1e32e7b3f301642a60448700ec531df981269 https://git.kernel.org/stable/c/a1d4941d9a24999f680799f9bbde7f57351ca637 https://git.kernel.org/stable/c/5289795824b77489803b0802cd9edc13824a2d0b https://git.kernel.org/stable/c/2d00158a06efe6bbcd020108634ea0f2ed8b32f7 https://git.kernel.org/stable/c/579944b9f38727d9ff570b58f83bc424e8af8398 https://git.kernel.org/stable/c/311242c7703df0da14c206260b7e855f69cb0264
