+Subject: [PATCH] lavd/v4l2: Use proper field type for second parameter of
+ ioctl() with BSD's
+
+The proper type was used until 73251678c83cbe24d08264da693411b166239bc7.
+
+This covers all of the OS's that currently have V4L2 support, permutations
+of Linux glibc/musl, Android bionic, FreeBSD, NetBSD, OpenBSD, Solaris.
+
+Copied from FreeBSD ports patch.

+Instead of relying on system #ifdefs which may or may not be correct,
+detect the POSIX ioctl signature at configure time.
