[PATCH] spi: axiado: Remove redundant pm_runtime_mark_last_busy() call
Posted by Felix Gu 1 month ago
The pm_runtime_mark_last_busy() call is redundant in the probe function
as pm_runtime_put_autosuspend() already calls pm_runtime_mark_last_busy()
internally to update the last access time of the device before queuing
autosuspend.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-7.1

Thanks!

[1/1] spi: axiado: Remove redundant pm_runtime_mark_last_busy() call
      https://git.kernel.org/broonie/misc/c/ec6c2e15a42f

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

How do you think about to construct another coccicheck script
for such a source code transformation pattern?
