Dave Young faf8c714f4 param_sysfs_builtin memchr argument fix
If memchr argument is longer than strlen(kp->name), there will be some
weird result.

It will casuse duplicate filenames in sysfs for the "nousb".  kernel
warning messages are as bellow:

sysfs: duplicate filename 'usbcore' can not be created
