From 0cc2effbc8f522af6b9d871cd27678e6aed9d56c Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Mon, 21 Apr 2025 16:32:09 -0500 Subject: [PATCH] HID: amd_sfh: Fix SRA sensor when it's the only sensor On systems that only have an SRA sensor connected to SFH the sensor doesn't get enabled due to a bad optimization condition of breaking the sensor walk loop. This optimization is unnecessary in the first place because if there is only one device then the loop only runs once. Drop the condition and explicitly mark sensor as enabled.
