Subject: [RFC] [PATCH v2 07/11] spi: Remove the now unused ctlr->idling flag
Date: Wed, 15 Jun 2022 14:46:30 +0200	[thread overview]
Message-ID: <20220615124634.3302867-8-david@protonic.nl> (raw)
In-Reply-To: <20220615124634.3302867-1-david@protonic.nl>

The ctlr->idling flag is never checked now, so we don't need to set it
either.
