commit 1e87a2456b0227ca4ab881e19a11bb99d164e792 upstream.

[jkosina@suse.cz: changed report->maxfield < 1 to report->maxfield != 1 as suggested by Bruno].

HID: provide a helper for validating hid reports

2013-10-01T16:10:51Z

commit 331415ff16a12147d57d5c953f3a961b7ede348b upstream. Many drivers need to validate the characteristics of their HID report during initialization to avoid misusing the reports. This adds a common helper to perform validation of the report exisitng, the field existing, and the expected number of values within the field.
