Subject: [PATCH] fbcon: Replace printk() with pr_*()
Date:   Sun,  1 Nov 2020 09:49:04 -0500
Message-Id: <20201101144904.1522611-1-yepeilin.cs@gmail.com>
In-Reply-To: <20201101094718.GD1166694@ravnborg.org>

Replace printk() with pr_err(), pr_warn() and pr_info(). Do not split long
strings, for easier grepping. Use `__func__` whenever applicable.

fbcon_prepare_logo() has more than one callers, use "fbcon_prepare_logo:"
instead of "fbcon_init:", for less confusion.
