Subject: staging: rtl8723bs: Replace yield() call with cond_resched()
X-Git-Tag: v4.17-rc1~124^2~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=c22da34a1b9996ffc6aadb4804422e04fe28b7e1;p=thirdparty%2Fkernel%2Flinux.git

staging: rtl8723bs: Replace yield() call with cond_resched()

Remove yield call(). yield does not guarantee progress, and should not
be used. cond_resched() is a safe alternative.
