[PATCH 6.9 135/157] ALSA: ump: Dont clear bank selection after sending a program change

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



6.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@xxxxxxx>

commit fe85f6e607d75b856e7229924c71f55e005f8284 upstream.

The current code clears the bank selection MSB/LSB after sending a
program change, but this can be wrong, as many apps may not send the
full bank selection with both MSB and LSB but sending only one.
Better to keep the previous bank set.
