Subject: lib/generic-radix-tree.c: remove unneeded __rcu
X-Git-Tag: v5.15~3116^2~82
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0a650e472d2039a5f768acd82f2a7068bf338dfd;p=platform%2Fkernel%2Flinux-starfive.git

lib/generic-radix-tree.c: remove unneeded __rcu

struct __genradix is defined as having its member 'root'
annotated as __rcu. But in the corresponding API RCU is not used.
Sparse reports this type mismatch as:
	lib/generic-radix-tree.c:56:35: warning: incorrect type in initializer (different address spaces)
	lib/generic-radix-tree.c:56:35:    expected struct genradix_root *r
	lib/generic-radix-tree.c:56:35:    got struct genradix_root [noderef] <asn:4> *__val
with 6 other ones.

So, correct root's type by removing this unneeded __rcu.
