Should I still return an error, even if the caller didn't check it?
Based on my understanding, the calibration function is used to make the signal more stable. Most of the time, mtkaif still works, even though the calibration fails. I guess that's why the caller(I refered to the implementation of mt8192.) didn't check the return value of calibration function.

DL7, UL1 and UL6 connect to the specific HWs separately. In such path, FE is required to enabled before BE because of the HW design.

Should I still return an error, even if the caller didn't check it?
Based on my understanding, the calibration function is used to make the signal more stable. Most of the time, mtkaif still works, even though the calibration fails. I guess that's why the caller(I refered to the implementation of mt8192.) didn't check the return value of calibration function.

See https://www.kernel.org/doc/html/latest/process/license-rules.html?highlight=...
Loadable kernel modules also require a MODULE_LICENSE() tag. This tag is neither a replacement for proper source code license information (SPDX-License-Identifier) nor in any way relevant for expressing or determining the exact license under which the source code of the module is provided.
“GPL”
Module is licensed under GPL version 2. This does not express any distinction between GPL-2.0-only or GPL-2.0-or-later. The exact license information can only be determined via the license information in the corresponding source files.
“GPL v2”
Same as “GPL”. It exists for historic reasons.
So "GPL v2" is not incorrect but for new contributions you might as well use the recommended tag.

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
