From c03dd939051403cb81bc33f397d47d0bde5e2aee Mon Sep 17 00:00:00 2001 From: Maxim Kochetkov Date: Fri, 5 May 2023 09:28:20 +0300 Subject: [PATCH] ASoC: dwc: limit the number of overrun messages [ Upstream commit ab6ecfbf40fccf74b6ec2ba7ed6dd2fc024c3af2 ] On slow CPU (FPGA/QEMU emulated) printing overrun messages from interrupt handler to uart console may leads to more overrun errors. So use dev_err_ratelimited to limit the number of error messages.
