Subject: [PATCH v3] platform/x86: intel-hid: fix _DSM function index handling
Date: Tue, 17 May 2022 20:31:30 +0200	[thread overview]
Message-ID: <66f813f5bcc724a0f6dd5adefe6a9728dbe509e3.camel@mniewoehner.de> (raw)
In-Reply-To: <CAHp75VcoLqByXy_VdhAu-j9oU_cL7FhdcegG=ePGkNK=cD+wKA@mail.gmail.com>

intel_hid_dsm_fn_mask is a bit mask containing one bit for each function
index. Fix the function index check in intel_hid_evaluate_method
accordingly, which was missed in commit 97ab4516205e ("platform/x86:
intel-hid: fix _DSM function index handling").
