Subject: drm/radeon/kms: evergreen & ni reset SPI block on CP resume
From: Jerome Glisse <jgli...@redhat.com>
commit a49a50dad48586d42ebac1a6730c3a3cd5603421 upstream.
For some reason SPI block is in broken state after module
unloading. This lead to broken rendering after reloading
module. Fix this by reseting SPI block in CP resume function
