drivers/char/dsp56k.c: drop check for negativity of unsigned parameter
[linux-3.16-rc5/drivers/char/dsp56k.c:386]: (style) Checking if unsigned variable 'arg' is less than zero. Source code is if (arg > 31 || arg < 0) return -EINVAL; But static long dsp56k_ioctl(struct file *file, unsigned int cmd, unsigned long arg) Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=80411 Reported-by: David Binderman <dcb314@hotmail.com> Signed-off-by: Andrey Utkin <andrey.krieger.utkin@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
