Regardless it's\na good idea to check for the error explicitly to avoid divide-by-zero.\n\nFixes the following warning:\n\n  drivers/pwm/pwm-mediatek.o: warning: objtool: .text: unexpected end of section\n\n[ukleinek: s/CONFIG_CLK/CONFIG_HAVE_CLK/]","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":5.5},"cwes":["CWE-369"],"references":["https://git.kernel.org/stable/c/4cb15042b5f3ec0474e91cf379120cc597625dbb","https://git.kernel.org/stable/c/77fb96dbe350e8a5ae4965ff9f6e7049f3966a6b","https://git.kernel.org/stable/c/7ca59947b5fcf94e7ea4029d1bd0f7c41500a161","https://git.kernel.org/stable/c/8b9f60725d74b72c238e4437c957d0217746b506","https://git.kernel.org/stable/c/8ddbec73ea2598d8414e8f7103241b55cf877010"],"products":["debian:debian_linux","linux:linux_kernel"],"source":"nvd","synced_at":"2026-10-19T22:01:22.920403922+00:00"},"epss":{"cve":"CVE-2025-37850","score":0.00298,"percentile":0.22564,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
