Subject: net/rxrpc: Use BUG_ON
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=163e3cb7daa8c3a6dde6a13a3d09a198930c6822;p=openwrt%2Fstaging%2Fblogic.git

net/rxrpc: Use BUG_ON

if (...) BUG(); should be replaced with BUG_ON(...) when the test has no
side-effects to allow a definition of BUG_ON that drops the code completely.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@ disable unlikely @ expression E,f; @@

(
  if (<... f(...) ...>) { BUG(); }
|
- if (unlikely(E)) { BUG(); }
+ BUG_ON(E);
)

@@ expression E,f; @@

(
  if (<... f(...) ...>) { BUG(); }
|
- if (E) { BUG(); }
+ BUG_ON(E);
)
// </smpl>
