From 082b86919b7a94de01d849021b4da820a6cb89dc Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 8 Oct 2025 12:55:18 +0300 Subject: [PATCH] media: v4l2-mem2mem: Fix outdated documentation Commit cbd9463da1b1 ("media: v4l2-mem2mem: Avoid calling .device_run in v4l2_m2m_job_finish") deferred calls to .device_run() to a work queue to avoid recursive calls when a job is finished right away from .device_run(). It failed to update the v4l2_m2m_job_finish() documentation that still states the function must not be called from .device_run(). Fix it.
