From: Jacopo Mondi Date: Sun, 10 Aug 2025 01:30:28 +0000 (+0300) Subject: media: imx-jpeg: Access v4l2_fh from file X-Git-Tag: v6.18-rc1~133^2~392 X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8be69363d852a355323a715fdfb558c6ea132cca;p=thirdparty%2Flinux.git media: imx-jpeg: 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.
