[PATCH AUTOSEL 6.14 07/27] HID: pidff: Add PERMISSIVE_CONTROL quirk

[Sasha Levin <sashal@kernel.org>]

From: Tomasz Pakuła <tomasz.pakula.oficjalny@gmail.com>

[ Upstream commit a4119108d2530747e61c7cbf52e2affd089cb1f6 ]

With this quirk, a PID device isn't required to have a strict
logical_minimum of 1 for the the PID_DEVICE_CONTROL usage page.

Some devices come with weird values in their device descriptors and
this quirk enables their initialization even if the logical minimum
of the DEVICE_CONTROL page is not 1.

Fixes initialization of VRS Direct Force Pro

Changes in v6:
- Change quirk name to better reflect it's intention
