[PATCHv2] spi: orion: use devm_clk_get_optional_enabled for axi clock
Posted by Rosen Penev 1 week, 1 day ago
Replace the open-coded optional axi clock get/prepare/enable and the
manual cleanup in probe/remove/runtime_resume with the managed helper
devm_clk_get_optional_enabled(). This removes the now-unused
out_rel_axi_clk error path and simplifies the clock lifecycle.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git for-7.3

Thanks!

[1/1] spi: orion: use devm_clk_get_optional_enabled for axi clock
      https://git.kernel.org/broonie/spi/c/61c2eaa653c2

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
