%autopatch -p1 prints warnings when no patches are found

[gotmax23]

Describe the bug

The go2rpm specfile template includes %autopatch -p1 by default to automatically apply patches if they are present after calling %goprep -A which calls %autosetup -N internally. In the latest RPM version, %autopatch prints out autopatch: no matching patches in range when no patches are defined.

To Reproduce
Steps to reproduce the behavior:

1. See golang-github-jba-templatecheck as an example or create a %prep section with

   %autosetup -N
   %autopatch -p1
   

2. Build

Expected behavior

rpmbuild should not print warnings.

Output

RPM build warnings:
    /builddir/build/SPECS/golang-github-jba-templatecheck.spec line 36: autopatch: no matching patches in range
(...)
warning: /builddir/build/SPECS/golang-github-jba-templatecheck.spec line 36: autopatch: no matching patches in range

You can suppress the warning with -q to %autosetup.

But, it shouldn't really complain in this case. The warning is mostly only meaningful with the -m/-M arguments.
