stable inclusion from stable-v4.19.312 commit 5533686e99b04994d7c4877dc0e4282adc9444a2 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L5G5 CVE: CVE-2024-26966

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...

--------------------------------

[ Upstream commit a903cfd38d8dee7e754fb89fd1bebed99e28003d ]

The frequency table arrays are supposed to be terminated with an empty element. Add such entry to the end of the arrays where it is missing in order to avoid possible out-of-bound access when the table is traversed by functions like qcom_find_freq() or qcom_find_freq_floor().

Only compile tested.
