Subject: IB/rxe: Don't check for null ptr in send()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5cc8fabc5e4c588c75a5ec21423e7c3425f69f48;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

IB/rxe: Don't check for null ptr in send()

pkt->qp was already dereferenced earlier in the function.

Fixes Smatch complaint:
drivers/infiniband/sw/rxe/rxe_net.c:458 send()
	 warn: variable dereferenced before check 'pkt->qp' (see line 441)
