spi: tegra114: Simplify with dev_err_probe()
Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and the error value gets printed. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20200901152713.18629-10-krzk@kernel.org Signed-off-by: Mark Brown <broonie@kernel.org>
