Subject: [PATCH] spi: bcm63xx-hsspi: fix controller deregistration
Make sure to deregister the controller before disabling underlying
resources like interrupts during driver unbind to allow SPI drivers to
do I/O during deregistration.
Note that clocks were also disabled before the recent commit
e532e21a246d ("spi: bcm63xx-hsspi: Simplify clock handling with
devm_clk_get_enabled()").
Fixes: 7d255695804f ("spi/bcm63xx-hsspi: use devm_register_master()")
