From: Jacopo Mondi Date: Sun, 10 Aug 2025 01:30:40 +0000 (+0300) Subject: media: s5p-mfc: Access v4l2_fh from file X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fede1dac719e080f922b52ef36fbb124dc1a2386;p=users%2Fhch%2Fmisc.git media: s5p-mfc: 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.
