Fix the use of to_usb_interface() without a hid_is_usb() check. I have verified that it is currently possible to trigger a kernel splat due to this bug in an ASAN build, and that this commit fixes the issue. The Linux kernel CVE team has assigned CVE-2026-80774 to this issue.

Unaffected versions might change over time as fixes are backported to older supported kernel versions.

Affected files ============== The file(s) affected by this issue are: drivers/hid/hid-asus.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/bdb2e0a2a359e473ca5619e35adee89028697239 https://git.kernel.org/stable/c/8b5debb6252cd1e2b6c7adf8f95761a0e743d2cf https://git.kernel.org/stable/c/1ddc2f5913bec7a846544d51a8f7a8119573b2a1 https://git.kernel.org/stable/c/ee883906cf6685d753af9c2d2ca9fd6f63197726 https://git.kernel.org/stable/c/02bf61dfb44f17ec187d1da1a82495951bbd12df
