From 214f525255069a55b4664842c68bc15b2ee049f0 Mon Sep 17 00:00:00 2001 From: Zev Weiss Date: Wed, 10 Nov 2021 18:53:38 -0800 Subject: hwmon: (nct6775) mask out bank number in nct6775_wmi_read_value() The first call to nct6775_asuswmi_read() in nct6775_wmi_read_value() had been passing the full bank+register number instead of just the lower 8 bits. It didn't end up actually causing problems because the second argument of that function is a u8 anyway, but it seems preferable to be explicit about it at the call site (and consistent with the rest of the code).
