Fix the bound check to also cover the UINT_MAX case. The Linux kernel CVE team has assigned CVE-2026-93046 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/base/swnode.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/6cde06887487b4febd14658c9a246616abcc0097 https://git.kernel.org/stable/c/0631384eadebc66d92d2dd72d57a0263c3877bee https://git.kernel.org/stable/c/b2fa4e8c7e4a33e02e6aaa8f6df72f84cf4aed75 https://git.kernel.org/stable/c/4ebf96d5f834aba7f6d0397db4c421f6078171b9 https://git.kernel.org/stable/c/849076df15129e47dd8db751fa18489419ffea56 https://git.kernel.org/stable/c/df5466412b362db7adfa78e3e092fe07ac6769a4 https://git.kernel.org/stable/c/231bbc04c58f115a505bf3b668ec69ef40a1773b https://git.kernel.org/stable/c/ba3dedcf3bd47017307595a7e54924198f018246
