Subject: [PATCH] input synaptics-rmi4: Eliminate packed structs in rmi_f11.c
Date: Tue, 10 Dec 2013 18:39:54 -0800 [thread overview]
Message-ID: <1386729594-5471-1-git-send-email-cheiny@synaptics.com> (raw)
This converts rmi_f11.c from using bitfields in packed structs, converting
to bitmasks and shifts to parse out bitfields, nibbles, and so on.
