Subject: [PATCH 1/2] Documentation: Bump media IOCTL reserved numbers
Date: Mon, 26 May 2025 14:17:31 +0300 [thread overview]
Message-ID: <20250526111732.487229-2-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20250526111732.487229-1-sakari.ailus@linux.intel.com>
The Media Controller uses IOCTL numbers up to 0x81. Given that nothing
appears to be using them for other purposes, even in the samples
allocation (checked with $ git grep "#define.*_IO.*'|'"), just reassign
the numbers up to 0x8f to linux/media.h and bump the samples allocation by
0x10.
