Subject: of: remove HAVE_ARCH_DEVTREE_FIXUPS
X-Git-Tag: v3.13-rc1~117^2~21
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=32df8dca503f82c816f8be85a8d0a394a8b88c2c;p=linux.git

of: remove HAVE_ARCH_DEVTREE_FIXUPS

HAVE_ARCH_DEVTREE_FIXUPS appears to always be needed except for sparc,
but it is only used for /proc/device-teee and sparc does not enable
/proc/device-tree. So this option is redundant. Remove the option and
always enable it. This has the side effect of fixing /proc/device-tree
on arches such as arm64 which failed to define this option.
