From a66a6eb9db10bd630bacf31e33505302c8e8303c Mon Sep 17 00:00:00 2001 From: "Edward A. James" Date: Thu, 10 Aug 2017 16:57:47 -0500 Subject: [PATCH] hwmon: (pmbus): Switch status registers to 16 bit Switch the storage of status registers to 16 bit values. This allows us to store all the bits of STATUS_WORD. Signed-off-by: Edward A.
