Subject: [PATCH 06/14] spi: dw: Log status register on timeout
Date: Sun, 31 Jan 2021 19:34:28 -0500	[thread overview]
Message-ID: <20210201003436.1180667-7-seanga2@gmail.com> (raw)
In-Reply-To: <20210201003436.1180667-1-seanga2@gmail.com>

This logs the status register on timeout, so it is easier to determine the
cause of the failure.
