In the reference HID sensor hub firmware all Named array enums were 0-based. There is no description of the default base of enums in HID sensor hub specification as logical minimum should have set this base value. Every sensor hub implemented enum as 1-based, without explicitly setting logical minimum to 1, because of the implementation by one of the major OS vendor. In Linux we used logical minimum to decide the enum base. Some sensor hub FWs already changed logical minimum from 0 to 1. We hoped that every other vendor will follow. But that didn't happen and we had to fix the report header for every sensor hub to change logical minimum to 1 by using .report_fixup() callback. So for every new sensor hub we had to modify source code by adding this quirk based on the vendor and device id. This is becoming a maintenance burden. This patch hardcodes the logical minimum of power and report state attributes to 1. In this way we can remove the existing quirks and also we don't have to add more quirks.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
