Subject: [PATCH v4 0/2] Add reset/enable GPIO support to SPI driver

I made a mistake last night when checking whether gpiod_set_value() is
safe to call with a NULL gpiod descriptor (it is).  v4 of the patch
just fixes that mistake.  It does simplify the code nicely.

This version also fixes the error handling when the reset gpio is
missing.
