If so I am sure we will need a bunch of similar patches which I don't think really help improve mwifiex quality Actually in its successor Nxpwifi (currently under review), we have cleaned up all indent, and checkpatch errors/warnings/checks.

BTW you advertised nxpwifi not as a successor to mwifiex, but as the driver to be used for new chips. This means we still have to deal with the mwifiex driver in the future to support the old chips, so even if nxpwifi is merged it still makes sense to clean up mwifiex. Sascha

Mwifiex has so many issues. As the driver will only support legacy devices and the state of it is "Odd fixes", It is better to fix really bugs of Mwifiex instead of cleanup it. David

The way you use "legacy" is from a silicon vendors perspective. Many real users only start to use a chip when it's already legacy for the silicon vendor. Sascha
