Subject: mips: setup: fix setnocoherentio() boolean setting
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=a664bd7a0084f0876ce2229d7894af485ef9e98f;p=linux.git

mips: setup: fix setnocoherentio() boolean setting

commit 1e6ae0e46e32749b130f1823da30cea9aa2a59a0 upstream.

Correct a typo/pasto: setnocoherentio() should set
dma_default_coherent to false, not true.

Fixes: 14ac09a65e19 ("MIPS: refactor the runtime coherent vs noncoherent DMA indicators")
