Subject: hwmon: (ntc_thermistor) Ensure that data->name string is terminated
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0ef63e48f0247a9f9b9ffeef0f2641ac880728ab;p=linux-beck.git

hwmon: (ntc_thermistor) Ensure that data->name string is terminated

Fix Coverity warning: Calling strncpy with a maximum size argument of 20 bytes
on destination array "data->name" of size 20 bytes might leave the destination
string unterminated.

Fix by replacing strncpy() with strlcpy() and by using sizeof() to determine
the maximum string length.
