Subject: [PATCH 1/4] spi: mt7621: Fix an error message in mt7621_spi_probe()
Date:   Sat, 27 Aug 2022 13:42:07 +0200
Message-Id: <928f3fb507d53ba0774df27cea0bbba4b055993b.1661599671.git.christophe.jaillet@wanadoo.fr>

'status' is known to be 0 at this point. The expected error code is
PTR_ERR(clk).

Switch to dev_err_probe() in order to display the expected error code (in a
human readable way).
This also filters -EPROBE_DEFER cases, should it happen.
