[PATCH v2] soundwire: qcom: fix device status array range
by Srinivas Kandagatla 01 Sep '22

01 Sep '22

This patch updates device status array range from 11 to 12 as we will be reading status from device number 0 to device number 11 inclusive. Without this patch we can potentially access status array out of range during auto-enumeration.
