CRIT KERN spi spi0.0: Resources present before probing Krishna, can you resend this with the following fixes tag? Fixes: f89d2cc3967a ("spi: tegra210-quad: use devm call for cdata memory") May be worth sending this separately from the reset of the series if that still needs work. Also, it could be worth indicating that this fixes the above error that we are observing and that the wrong device was being used for devm. Otherwise ...
