As long as sun4i/sun6i SPI drivers have overriden the default
"wait for completion" procedure then we need to properly
handle -ETIMEDOUT error from transfer_one().
Why is this connected to those drivers specifically?
These 2 drivers have their own "waiting" code and not using the code from
SPI core.
Does this not apply to any other driver - why is this something we only
have to do when these drivers do it? That's what's setting off alarm
bells.
sun4i/sun6i drivers have let's say "smart" waiting while SPI core uses a
fixed interval to wait.
I can't say for every SPI driver in kernel, that's outside of my area of
expertise.
