X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=192125e0909e106ae37c2447ec43ee2653909d17;p=thirdparty%2Flinux.git

gpu: nova-core: falcon: remove unwarranted safety check in dma_load

This safety check was an assumption based on the firmwares we work with
- it is not based on an actual hardware limitation. Thus, remove it.
