Message-Id: <7a5cfe63cad3ef4badc30cbc2185a5bfb9250fd8.1483813334.git.joe@perches.com>
Date: Sat, 7 Jan 2017 10:32:30 -0800
From: Joe Perches <joe@...ches.com>

Subject: [RFC PATCH] intel: Use upper_32_bits and lower_32_bits
Shifting and masking various types can be made a bit
simpler to read by using the available kernel macros.
Signed-off-by: Joe Perches <joe@...ches.com>
---
This RFC patch is meant as an example, not necessarily
to apply, though it does compile to equivalent code.
It does seem a bit simpler for a human to read.
Perhaps this could be automated via a coccinelle script,
but this was done with grep & sed and some typing.
Treewide, there are many hundred instances of this style code
that could be converted.
Dunno if it's really worth it though.
Another usage that could be converted is DMA_BIT_MASK(32)
where it is equivalent to upper_32_bits and lower_32_bits.
