[ Upstream commit c3fc002b206c6c83d1e3702b979733002ba6fb2c ]
rsnd_kctrl_accept_runtime() (1) is used for runtime convert rate (= Synchronous SRC Mode). Now, rsnd driver has 2 kctrls for it
(A): "SRC Out Rate Switch" (B): "SRC Out Rate" // it calls (1)
(A): can be called anytime (B): can be called only runtime, and will indicate warning if it was used at non-runtime.
To use runtime convert rate (= Synchronous SRC Mode), user might uses command in below order.
(X): > amixer set "SRC Out Rate" on > aplay xxx.wav & (Y): > amixer set "SRC Out Rate" 48010 // convert rate to 48010Hz
(Y): calls B (X): calls both A and B.
In this case, when user calls (X), it calls both (A) and (B), but it is not yet start running. So, (B) will indicate warning.
This warning was added by commit b5c088689847 ("ASoC: rsnd: add warning message to rsnd_kctrl_accept_runtime()"), but the message sounds like the operation was not correct. Let's update warning message.
The message is very SRC specific, implement it in src.c
