+Subject: [PATCH] staging: bcm2835-codec: Correct buffer number
+ change on start streaming
+
+"cac8c90 staging: vc04_service: codec: Allow start_streaming to update
+the buffernum" allowed the number of buffers configured to be decreased
+as well as increased, but there is no requirement for all buffers to
+have been queued when start_streaming is called.
+
+Only allow increasing the buffernum.
+
+Fixes: "cac8c90 staging: vc04_service: codec: Allow start_streaming to update the buffernum"
