Subject: s390: drop CONFIG_VIRT_TO_BUS
X-Git-Tag: v5.15~6484^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=964d06b4ed212d85ff589a9438baeb6c4fff3272;p=platform%2Fkernel%2Flinux-starfive.git

s390: drop CONFIG_VIRT_TO_BUS

VIRT_TO_BUS is only used for legacy device PCI and ISA drivers using
virt_to_bus() instead of the streaming DMA mapping API, and the
remaining drivers generally don't work on 64-bit architectures.

Two of these drivers also cause a build warning on s390, so instead
of trying to fix that, let's just disable the option as we do on
most architectures now.
