From 7a089ec7d77fe7d50f6bb7b178fa25eec9fd822b Mon Sep 17 00:00:00 2001 From: Peilin Ye Date: Thu, 12 Nov 2020 07:04:03 -0500 Subject: [PATCH] console: Delete unused con_font_copy() callback implementations Recently in commit 3c4e0dff2095 ("vt: Disable KD_FONT_OP_COPY") we disabled the KD_FONT_OP_COPY ioctl() option. Delete all the con_font_copy() callbacks, since we no longer use them. Mark KD_FONT_OP_COPY as "obsolete" in include/uapi/linux/kd.h, just like what we have done for PPPIOCDETACH in commit af8d3c7c001a ("ppp: remove the PPPIOCDETACH ioctl").
