redefined regmap_read_poll_timeout and regmap_field_read_poll_timeout
by read_poll_timeout to simplify code, they have many similar codes.

use read_poll_timeout macro to redefined regmap_read_poll_timeout
and also remove the duplicate code.

[1/2] regmap: Simplify implementation of the regmap_read_poll_timeout() macro
commit: e44ab4e14d6f4c448ae555132090c1a116b19e5c
[2/2] regmap: Simplify implementation of the regmap_field_read_poll_timeout() macro
commit: 148c01d176237115d9c2805f6d29c0b6a72fbd10
All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
Thanks,
Mark
