[PATCH] iio: adc: ad4080: fix AD4880 chip ID
From: Antoniu Miclaus
Date: Tue Jun 02 2026 - 04:47:04 EST
The AD4880 chip ID was incorrectly set to 0x0750. According to the
datasheet, the product ID registers read 0x00 (PRODUCT_ID_H) and 0x59
(PRODUCT_ID_L), giving a combined chip ID of 0x0059. Fix the value to
match the actual hardware.
