The value of such a patch is marginal. The compiler will optimize it and only
calculate the value of rate[i] & 0x7f once, and keep it in a register, which is
likely what happens with your change as val will never be used again. Checkpatch
is only suggestive and can be ignored.
You have no signed-off-by tag. As such, this patch could never be applied as it
has no one vouching that they are the author. Please read and follow the
instructions for submitting patches.
