From c93f5463e35a95c8cad5deb4ad5d32b0eb913abd Mon Sep 17 00:00:00 2001 From: kbuild test robot Date: Fri, 1 May 2015 00:27:35 +0800 Subject: [PATCH] staging: lustre: fix ifnullfree.cocci warnings drivers/staging/lustre/lustre/lov/lov_obd.c:574:3-8: WARNING: NULL check before freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or usb_free_urb is not needed. Maybe consider reorganizing relevant code to avoid passing NULL values. NULL check before some freeing functions is not needed. Based on checkpatch warning "kfree(NULL) is safe this check is probably not required" and kfreeaddr.cocci by Julia Lawall.
