From b7d52b2152e5d3b7f72f27c813df9cc402c4dca0 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Thu, 17 Jan 2019 00:22:48 +0000 Subject: [PATCH] media: em28xx: Fix misplaced reset of dev->v4l::field_count The backport of commit afeaade90db4 "media: em28xx: make v4l2-compliance happier by starting sequence on zero" added a reset on em28xx_v4l2::field_count to em28xx_ctrl_notify(), but it should be done in em28xx_start_analog_streaming().
