Subject: [PATCH] spi: Probe spi devices without alias
Date: Tue, 10 Jun 2025 17:24:56 +0200 [thread overview]
Message-ID: <20250610-imx_spi_alias-v1-1-fc23f2f143ea@pengutronix.de> (raw)
Continue probing spi connected devices without an alias. Setting bus_num
to -1 will assign numbers automatically.
