Subject: [PATCH 5.15 031/667] platform/x86: intel-hid: fix _DSM function index handling

From: Michael Niewöhner <linux@...ewoehner.de>

commit 1620c80bba53af8c547bab34a1d3bc58319fe608 upstream.

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").
