+Subject: [PATCH] ms_adpcm: Fix and extend size checks
+
+'blockalign' is the size of a block, and each block contains 7 samples
+per channel as part of the preamble, so check against 'samplesperblock'
+rather than 'blockalign'. Also add an additional check that the block
+is big enough to hold the samples it claims to hold.
