-Subject: [PATCH] Revert "aplay: fix pcm_read() return value"
-
-This reverts commit 8aa13eec80eac312e4b99423909387660fb99b8f.
-
-The semantics for pcm_read() and pcm_readv() was changed, but the
-callers expect the exact frame count as requested. It's possible
-to fix callers, but the fix is more complicated than to revert the
-change. Note that '-d' processing was broken in some cases.
-
-Note: The reverted commit allows that the return value might be
-greater than requested (see the first condition in read routines).
