From a41a8927e7adfa5de607d5bd43fa8fbbef44d6f2 Mon Sep 17 00:00:00 2001 From: Guenter Roeck Date: Sat, 22 Feb 2014 08:17:34 -0800 Subject: hwmon: (lm95245) Make temp2_crit_hyst read-only The hysteresis register is shared among both temperature sensors. This means changing one also affects the other. To avoid confusion, established way to express this is to make only the first instance writable and keep all other instances as read-only. Otherwise users may be confused that changing the second writable value also affects the first, while it is more obvious that a writable value may affect a different read-only value.
