[PATCHv13 8/9] serial: qcom_geni_serial: Disable MMIO tracing for geni serial

From: Sai Prakash Ranjan
Date: Thu Apr 28 2022 - 08:45:55 EST


Disable MMIO tracing for geni serial driver as it is a high
frequency operation for serial driver with many register reads/
writes and not very useful to log all MMIO traces and prevent
excessive logging.
