Subject: [PATCH][next] spi: Fix self assignment issue with ancillary->mode
Date: Wed, 23 Jun 2021 18:23:00 +0100	[thread overview]
Message-ID: <> (raw)

From: Colin Ian King <>

There is an assignment of ancillary->mode to itself which looks
dubious since the proceeding comment states that the speed and
mode is taken over from the SPI main device, indicating that
ancillary->mode should assigned using the value spi->mode.
Fix this.

Addresses-Coverity: ("Self assignment")
Fixes: 0c79378c0199 ("spi: add ancillary device support")
