From 1df3ae5358643ac1979729c09c5dd861b0e82a32 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 3 May 2021 13:57:27 +0200 Subject: [PATCH] Revert "media: gspca: mt9m111: Check write_bridge for timeout" This reverts commit a6f6f853b82d74a5a29fa685b3e2a754a2d28be9. Because of recent interactions with developers from @umn.edu, all commits from them have been recently re-reviewed to ensure if they were correct or not. Upon review, this commit was found to be incorrect for the reasons below, so it must be reverted. It will be fixed up "correctly" in a later kernel change. Different error values should never be "OR" together and expect anything sane to come out of the result.
