Subject: hte: tegra-194: Fix off by one in tegra_hte_map_to_line_id()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e078180d66848a6a890daf0a3ce28dc43cc66790;p=linux.git

hte: tegra-194: Fix off by one in tegra_hte_map_to_line_id()

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")
