Please check for false positives in the output before submitting a patch. When using "patch" mode, carefully review the patch before submitting it. drivers/crypto/qat/qat_dh895xcc/adf_isr.c:191:3-8: 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. drivers/crypto/qat/qat_dh895xcc/adf_isr.c:208:3-8: WARNING: NULL check before freeing functions like kfree, debugfs_remove, debugfs_remove_recursive or usb_free_urb is not needed.
