Subject: highmem: fix a memory copy problem in memcpy_from_folio
Date: Thu, 30 Nov 2023 11:40:18 +0800

Clang static checker complains that value stored to 'from' is never read. 
And memcpy_from_folio() only copy the last chunk memory from folio to
destination.  Use 'to += chunk' to replace 'from += chunk' to fix this
typo problem.
