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

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

I think map is tegra194_aon_gpio_map and map_sz is
ARRAY_SIZE(tegra194_aon_gpio_map) but I wasn't able to follow the code
all the way through.  Untested.
