From ecdcfa456e6f6048666c7dd56a0c9b95e50312a5 Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Sun, 10 Aug 2025 04:30:43 +0300 Subject: [PATCH] media: stm32: dma2d: Access v4l2_fh from file The v4l2_fh associated with an open file handle is now guaranteed to be available in file->private_data, initialised by v4l2_fh_add(). Access the v4l2_fh, and from there the driver-specific structure, from the file * in all ioctl handlers.
