Why did you only do these three files? uint8_t appears in other files
in ks7010/ also. Perhaps you could do all the files in one patch.

If you like you could do a patch set changing all the standard types
to kernel types. i.e one patch per type (uint8_t, uint16_t ...).

I have a patch set in flight that includes these type changes with
review asking me to do exactly  this. However, if you would like to do
it I will remove the type changes from my patch set and wait until yours is applied before
re-submitting.

Please let me know if you intend to do this.

Oh, and if you really want cudos you could add a bit more detail to
your git log, for example

Checkpatch emits warning ...

Change standard type uint8_t to kernel type u8.

Well done and good luck.

thanks,
Tobin.
