Subject: [PATCH v2 1/2] console: Remove dummy con_font_op() callback implementations
Date: Mon,  2 Nov 2020 04:36:05 -0500
Message-ID: <c5563eeea36aae7bd72ea2e985bc610d585ece40.1604306433.git.yepeilin.cs@gmail.com> (raw)
In-Reply-To: <c5563eeea36aae7bd72ea2e985bc610d585ece40.1604128639.git.yepeilin.cs@gmail.com>

`struct console_font` is a UAPI structure, thus ideally should not be
used for kernel internal abstraction. Remove some dummy .con_font_set,
.con_font_default and .con_font_copy `struct consw` callback
implementations, to make it cleaner.
