Subject: [PATCH 1/5] console: Delete unused con_font_copy() callback implementations
Date: Thu, 12 Nov 2020 07:04:03 -0500
Message-ID: <c8d28007edf50de4387e1532eb3eb736db716f73.1605169912.git.yepeilin.cs@gmail.com> (raw)
In-Reply-To: <cover.1605169912.git.yepeilin.cs@gmail.com>

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").
