[PATCH v1 7/8] iio: dac: ds4424: ratelimit read errors and use device context
From: Oleksij Rempel
Date: Mon Jan 19 2026 - 13:24:33 EST
Replace pr_err() with dev_err_ratelimited() in the RAW read path to avoid
log spam on repeated I2C failures and to include the device context.
Use %pe to print errno names for faster debugging.
