Subject: [PATCH printk v5 04/40] printk: register_console: use "registered" for variable names
Date: Wed, 16 Nov 2022 17:27:16 +0106	[thread overview]
Message-ID: <20221116162152.193147-5-john.ogness@linutronix.de> (raw)
In-Reply-To: <20221116162152.193147-1-john.ogness@linutronix.de>

The @bootcon_enabled and @realcon_enabled local variables actually
represent if such console types are registered. In general there
has been a confusion about enabled vs. registered. Incorrectly
naming such variables promotes such confusion.

Rename the variables to _registered.
