[PATCH] scripts/clang-tools: Remove DeprecatedOrUnsafeBufferHandling check

From: Guru Das Srinagesh
Date: Thu Aug 04 2022 - 13:46:37 EST


This `clang-analyzer` check flags the use of memset(), suggesting a more
secure version of the API, such as memset_s(), which does not exist in
the kernel:

warning: Call to function 'memset' is insecure as it does not provide
security checks introduced in the C11 standard. Replace with analogous
functions that support length arguments or provides boundary checks such
as 'memset_s' in case of C11
