From 66558537cb8c7485cf2d43b3880395c81218ec12 Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Date: Mon, 22 Jul 2024 11:52:26 +0000 Subject: [PATCH 1/4] media: uvcvideo: Fix custom control mapping probing Custom control mapping introduced a bug, where the filter function was applied to every single control. Fix it so it is only applied to the matching controls. The following dmesg errors during probe are now fixed: usb 1-5: Found UVC 1.00 device Integrated_Webcam_HD (0c45:670c) usb 1-5: Failed to query (GET_CUR) UVC control 2 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 3 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 6 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 7 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 8 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 9 on unit 2: -75 (exp. 1). usb 1-5: Failed to query (GET_CUR) UVC control 10 on unit 2: -75 (exp. 1).
