Subject: habanalabs: remove condition that is always true
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f0539fb0fb5fcb595bbb46dfe88c97e825f29f1f;p=openwrt%2Fstaging%2Fblogic.git

habanalabs: remove condition that is always true

After removing the parsing of the command submission
when doing memset of the device memory, goya_validate_dma_pkt_host
is never called by the kernel, so there is no need to check
context id.
