Subject: sched/core: Use -EINVAL in sched_dynamic_mode()
X-Git-Tag: v5.13-rc1~118^2~31
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c4681f3f1cfcfde0c95ff72f0bdb43f9ffd7f00e;p=thirdparty%2Fkernel%2Flinux.git

sched/core: Use -EINVAL in sched_dynamic_mode()

-1 is -EPERM which is a somewhat odd error to return from
sched_dynamic_write(). No other callers care about which negative
value is used.
