Hi Jonathan, Here it goes v3. Only thing that is not exactly closed is the 2 channels in the DAC driver. So, I kind of added a comment with something similar to my reply in v2 [1]. Full log: v1: * https://lore.kernel.org/all/20240328-iio-backend-axi-dac-v1-0-afc808b3fde3@xxxxxxxxxx/ v2: * https://lore.kernel.org/all/20240405-iio-backend-axi-dac-v2-0-293bab7d5552@xxxxxxxxxx v3: - Patch 3: * Align on open parenthesis. - Patch 8 * Removed asm-generic/errno-base.h; * Only use default (1 to 1 backend frontend) method to get backends. - Patch 10: * Add comment for having 2 different channels.
