From 9bb83e8fe252f15ad30430e80eb7f9da66cacbb9 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 13 Oct 2020 16:26:17 +0200 Subject: media: Bulk remove BUG_ON(in_interrupt()) None of these BUG_ON()'s is justified. BUG_ON() should only be used when there is really no way to survive. If at all these could be replaced by lockdep_assert_preemption_enabled() to cover all invalid caller context and not just those covered by in_interrupt(). But all functions which are invoked from those places contain already debug mechanisms to catch wrong context, so having these extra checks is not having any advantage.
