Don't populate the array clocks on the stack but instead it
static. Makes the object code smaller by 316 bytes.
Before:
text data bss dec hex filename

After:
text data bss dec hex filename

That's likely also compiled allyesconfig.
allyesconfig compilations create a lot of superfluous data and text.
It's rather smaller with a defconfig and just the driver selected.
And here are a few additional possibilities for this driver.

[1/1] ASoC: tlv320aic32x4: make array clocks static, makes object smaller
commit: ea9df9840fd5d766b9e98b0073890de4be68b062
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
