Subject: [PATCH] ALSA: sis7019: Use managed buffer allocation
Git-commit: ff3eb3d51be9d191fe3e663d0e95ed8b28824a89
Patch-mainline: v5.6-rc1
References: jsc#SLE-16518
Clean up the driver with the new managed buffer allocation API.
The hw_params and hw_free callbacks became superfluous and got
dropped.
