6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Hung alex.hung@amd.com
[ Upstream commit 3941a3aa4b653b69876d894d08f3fff1cc965267 ]
[WHY] fe_clk_en has size of 5 but sizeof(fe_clk_en) has byte size 20 which is lager than the array size.
[HOW] Divide byte size 20 by its element size.
This fixes 2 OVERRUN issues reported by Coverity.
