Pointers V4L2 pixelformat and dataformat fields in a few packed structs
are directly passed to printk family of functions. This could result in an
unaligned access albeit no such possibility appears to exist at the
moment i.e. this clang warning appears to be a false positive.
Address the warning by copying the pixelformat or dataformat value to a
local variable first.
