The patch below fixes the checkpatch complaints on kfree(): WARNING: kfree(NULL) is safe this check is probabally not required This patch has been verified as follows: - Verified that checkpatch does no longer complain about kfree(). - Verified that make -s clean && make -s iscsi scst && make -s -C srpt still works and does not trigger any new compiler warnings. - Checked that the patch generated by generate-kernel-patch still applies cleanly to the 2.6.25.4 kernel, and that the patched kernel tree still compiles, installs and boots fine, and that the iscsi-scst, ib_srpt, scst_disk and scst_vdisk modules still load. Note: I'm not sure any of the above verifications did trigger the code paths changed by this patch.
