[PATCH v2 0/3] Cleanup: Formatting iwlwifi driver

[PATCH v2 0/3] Cleanup: Formatting iwlwifi driver

[Juan José Arboleda]

Code Style Enhancements:

* Pointer Declarations: Improved spacing consistency.

Macro Improvements:

* Enclosed multi-statement macro in a do-while loop.

Formatting Standardization:

* Replaced spaces with tabs in iwl_mvm_vendor_events_idx.

This V2 fixes the compile issue. I had a small confussion with my kernel
configuration. Now it is tested/compiled.

Best regards,
Juan

[PATCH v2 1/3] iwlwifi: mvm: Improve code style in pointer declarations

[Juan José Arboleda]

The changes ensure that there is a space between the `u8` type and the
`*` character as preferred by the guidelines.

This change is purely stylistic and do not affect the functionality
of the code.

The current usage of CHECK_BW is already safe as it’s only used in standalone contexts where multi-statement expansion poses no risk.
NACK.
