Subject: [PATCH] hte: tegra-194: Fix off by one in tegra_hte_map_to_line_id()
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: e078180d66848a6a890daf0a3ce28dc43cc66790
[ Upstream commit e078180d66848a6a890daf0a3ce28dc43cc66790 ]
The "map_sz" is the number of elements in the "m" array so the >
comparison needs to be changed to >= to prevent an out of bounds
read.
Fixes: 09574cca6ad6 ("hte: Add Tegra194 HTE kernel provider")
