Subject: [PATCH v5 1/2] spi: Replace -ENOTSUPP with -EOPNOTSUPP in op checking
From: "Chia-Lin Kao (AceLan)" <acelan.kao@...onical.com>
No functional changes are introduced by this patch; it's a code cleanup
to use the correct error code.
Signed-off-by: Chia-Lin Kao (AceLan) <acelan.kao@...onical.com>
