Subject: net: ip, raw_diag -- Use jump for exiting from nested loop
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9999370faed945be2913cd34aa24e84317a0ceda;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: ip, raw_diag -- Use jump for exiting from nested loop

I managed to miss that sk_for_each is called under "for"
cycle so need to use goto here to return matching socket.
