Subject: [PATCH 6/9] iio: mcp9600: switch to using FIELD_GET_SIGNED()
Date: Fri, 17 Apr 2026 13:36:17 -0400 [thread overview]
Message-ID: <20260417173621.368914-7-ynorov@nvidia.com> (raw)
In-Reply-To: <20260417173621.368914-1-ynorov@nvidia.com>
Switch from sign_extend32(FIELD_GET()) to the dedicated
FIELD_GET_SIGNED() and don't calculate the fields length explicitly.
