[Fix]

* Cherry-pick c4da1205752d from upstream.
For SD cardreaders it is extremely common not to have a cache.
Consequently, these error messages do not point to a real error.
Change KERN_ERR to KERN_WARNING.

[Test Plan]

* Checked error message is gone after applying the patch.

[Where problems could occur]

* Low potential for regression.
