Subject: [PATCH linux-next] HID: amd_sfh: Fix max supported HID devices
Date: Mon, 24 Apr 2023 21:34:06 +0530	[thread overview]
Message-ID: <20230424160406.2579888-1-Basavaraj.Natikar@amd.com> (raw)

commit 4bd763568dbd ("HID: amd_sfh: Support for additional light sensor")
adds additional sensor devices, but forgets to add the number of HID
devices to match. Thus, the number of HID devices does not match the
actual number of sensors.

In order to prevent corruption and system hangs when more than the
allowed number of HID devices are accessed, the number of HID devices is
increased accordingly.

Fixes: 4bd763568dbd ("HID: amd_sfh: Support for additional light sensor")
