X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8ba53beb2ce30f5fd0abe1638440889d10988b7c;p=openwrt%2Fstaging%2Fblogic.git

Staging: lustre: ptlrpc: Remove unnecessary cast on void pointer

void pointers do not need to be cast to other pointer types.

The semantic patch used to find this:

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

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