Subject: [PATCH 4.19 074/229] spi: mt7621: Fix an error message in mt7621_spi_probe()

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 2b2bf6b7faa9010fae10dc7de76627a3fdb525b3 ]

'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.
