Subject: [PATCH v6 04/11] iio: adc: ti-ads1015: return -ENODATA when match data is missing
Date: Mon, 9 Nov 2026 22:21:32 +0530 [thread overview]
Message-ID: <20261109165139.30803-5-architanant5@gmail.com> (raw)
In-Reply-To: <20261109165139.30803-1-architanant5@gmail.com>
When i2c_get_match_data() returns NULL, it indicates that driver match
data is absent rather than an invalid argument being provided.
Return -ENODATA instead of -EINVAL to more accurately reflect the failure.
