fixed sparse warnings by adding a cast in assignment from void [noderef] __user * to unsigned int __force * and a reverse cast in argument from unsigned int * to unsigned int __user * . v1 -> v2: - Add a reverse cast in argument v2 -> v3: - Change commit description as suggested by Ian Abott v3 -> v4: - Add versioning information in commit description
For future reference, the patch change history should go below the "---" divider line below where git will ignore it so that it does not appear in the final commit description. Otherwise, the committer would need to edit it out manually.
