The commit e00b488e813f ("usb-storage: Add Hiksemi USB3-FW to IGNORE_UAS") blacklists UAS for all of RTL9210 enclosures.

The RTL9210 controller was advertised with UAS since its release back in 2019 and was shipped with a lot of enclosure products with different firmware combinations.

Blacklist UAS only for HIKSEMI MD202.

This should hopefully be replaced with more robust method than just comparing strings. But with limited information [1] provided thus far (dmesg when the device is plugged in, which includes manufacturer and product, but no lsusb -v to compare against), this is the best we can do for now.

Hi,

This is the friendly patch-bot of Greg Kroah-Hartman. You have sent him a patch that has triggered this response. He used to manually respond to these common problems, but in order to save his sanity (he kept writing the same thing over and over, yet to different people), I was created. Hopefully you will not take offence and will fix the problem in your patch and resubmit it so that it can be accepted into the Linux kernel tree.

You are receiving this message because of the following common error(s) as indicated below:

- This looks like a new version of a previously submitted patch, but you did not list below the --- line any changes from the previous version. Please read the section entitled "The canonical patch format" in the kernel file, Documentation/process/submitting-patches.rst for what needs to be done here to properly describe this.

If you wish to discuss this problem further, or you have questions about how to resolve this issue, please feel free to respond to this email and Greg will reply once he has dug out from the pending patches received from other developers.

thanks,

greg k-h's patch email bot
