[PATCH] spi: tegra114: Don't fail set_cs_timing when delays are zero

[Aaron Kling via B4 Relay <devnull+webgeek1234.gmail.com@kernel.org>]

From: Aaron Kling <webgeek1234@gmail.com>

The original code would skip null delay pointers, but when the pointers
were converted to point within the spi_device struct, the check was not
updated to skip delays of zero. Hence all spi devices that didn't set
delays would fail to probe.

Fixes: 04e6bb0d6bb1 ("spi: modify set_cs_timing parameter")
