From 28bc24fc46f9c9f39ddefb424d6072041805b563 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 15 Jun 2020 09:48:33 +0200 Subject: vc: separate state There are two copies of some members of struct vc_data. This is because we need to save them and restore later. Move these memebers to a separate structure called vc_state. So now instead of members like: vc_x, vc_y and vc_saved_x, vc_saved_y we have state and saved_state (of type: struct vc_state) containing state.x, state.y and saved_state.x, saved_state.y This change: * makes clear what is saved & restored * eases save & restore by using memcpy (see save_cur and restore_cur) Finally, we document the newly added struct vc_state using kernel-doc.
