Subject: ubifs: Force prandom result to __le32
X-Git-Tag: v5.15~4988^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3cfa4412df98207e07de6e60d3c805c541cbce1a;p=platform%2Fkernel%2Flinux-starfive.git

ubifs: Force prandom result to __le32

In set_dent_cookie() the result of prandom_u32() is
assinged to an __le32 type. Make this a forced conversion
to remove the following sparse warning:

fs/ubifs/journal.c:506:30: warning: incorrect type in assignment (different base types)
fs/ubifs/journal.c:506:30:    expected restricted __le32 [usertype] cookie
fs/ubifs/journal.c:506:30:    got unsigned int
