+Subject: [PATCH] Fix max channel count bug
+
+The code was allowing files to be written with a channel count of exactly
+`SF_MAX_CHANNELS` but was failing to read some file formats with the same
+channel count.
+
+Upstream-Status: Backport [https://github.com/erikd/libsndfile/
+commit/6f3266277bed16525f0ac2f0f03ff4626f1923e5]
