With this patch, when using a gpio CS, the hardware CS0 is always used. Thanks to this, there is no more limitation for the number of gpio CS we can use.

This is going to break any system where we use both a GPIO chip select and chip select 0. Ideally we'd try to figure out an unused chip select to use here...

The point is that this use case is already broken and this patch fixes the crash and is easily backportable.

Fixing the CS + gpio CS should probably be done in a separate patch.
