Subject: [PATCH 1/5] HID: lenovo: Merge tpkbd and cptkbd data structures
Date: Sat,  4 Jul 2020 15:27:38 +0200	[thread overview]
Message-ID: <20200704132742.60197-2-hdegoede@redhat.com> (raw)
In-Reply-To: <20200704132742.60197-1-hdegoede@redhat.com>

Merge the tpkbd and cptkbd data structures, into a single unified
structure instead of having a separate data structure per keyboard type.

This is a preparation patch for making the tpkbd LED functions more
generic, so that they can be re-used for supporting the LEDs on the
Thinkpad 10 ultrabook keyboard.
