[PATCH OLK-6.6] drm/amd/display: Fix index out of bounds in degamma hardware format translation

From: Srinivasan Shanmugam <srinivasan.shanmugam(a)amd.com> stable inclusion from stable-v6.6.55 commit 122e3a7a8c7bcbe3aacddd6103f67f9f36bed473 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYR9A CVE: CVE-2024-49894 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit b7e99058eb2e86aabd7a10761e76cae33d22b49f ] Fixes index out of bounds issue in `cm_helper_translate_curve_to_degamma_hw_format` function. The issue could occur when the index 'i' exceeds the number of transfer function points (TRANSFER_FUNC_POINTS). The fix adds a check to ensure 'i' is within bounds before accessing the transfer function points. If 'i' is out of bounds the function returns false to indicate an error.
