Date: Mon, 9 Nov 2026 03:52:38 +0000 Message-ID: <20261109035252.1295926-1-jic23@kernel.org> X-Mailer: git-send-email 2.56.0 X-Mailing-List: linux-kernel@vger.kernel.org List-Id: List-Post: List-Help: List-Subscribe: List-Unsubscribe: List-Owner: Precedence: list MIME-Version: 1.0 Content-Transfer-Encoding: 8bit From: Jonathan Cameron The primary aim here is to ensure a clean layering between the two sides of the trigger / pollfunc (push to buffers) divide. The caller of iio_trigger_poll() and iio_trigger_poll_nested() should be using data relevant to the trigger, not iio_dev->trig which is the current_trigger for the device. Most drivers got this layering right, but not this set! This is also step 1 in a plan to make iio_dev->trig opaque allowing more control of how it is assigned and avoiding traps around lifetimes. Includes one precursor fix that has been broken long enough I think we can just merge it via the slow path along with the rest of these.
