| Subject: ASoC: dwc: limit the number of overrun messages |
| |
| From: Maxim Kochetkov <fido_max@inbox.ru> |
| |
| [ 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. |
