[ Upstream commit a720416d94634068951773cb9e9d6f1b73769e5b ]
There's a spinlock in place that is taken in file_operations callbacks
whenever we check if spidev->spi is still alive (not null). It's also
taken when spidev->spi is set to NULL in remove().
There are ongoing discussions of race conditions with this commit.
Okay, I've dropped it. Thanks!
