From 7f2fc0e13ba2b9ecfd60a94a078e96f41e2f19d5 Mon Sep 17 00:00:00 2001 From: Yassine Oudjana Date: Tue, 4 Jan 2022 03:35:36 +0000 Subject: [PATCH] ASoC: wcd9335: Keep a RX port value for each SLIM RX mux Currently, rx_port_value is a single unsigned int that gets overwritten when slim_rx_mux_put() is called for any RX mux, then the same value is read when slim_rx_mux_get() is called for any of them. This results in slim_rx_mux_get() reporting the last value set by slim_rx_mux_put() regardless of which SLIM RX mux is in question. Turn rx_port_value into an array and store a separate value for each SLIM RX mux.
