Subject: [PATCH] kernfs: Drop cast
Date: Sat, 28 Jun 2014 19:04:28 +0530	[thread overview]
Message-ID: <20140628133428.GA4751@himangi-Dell> (raw)

This patch does away with cast on void * and the if as it is unnecessary.

The following Coccinelle semantic patch was used for making the change:

@r@
expression x;
void* e;
type T;
identifier f;
@@

(
  *((T *)e)
|
  ((T *)x)[...]
|
  ((T *)x)->f
|
- (T *)
  e
)
