Subject: staging: rdma: hfi1: Remove useless return variables
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6d210eef1b31b02ebec37a2ced6e73a1f94aacf1;p=linux-beck.git

staging: rdma: hfi1: Remove useless return variables

This patch removes unnecessary return variables and compresses the
return logic.

The coccinelle script that finds and fixes this issue is:

@@ type T; identifier i,f; constant C; @@
- T i;
...when != i
when strict
( return -C;
|
- i =
+ return
f(...);
- return i;
)
