From 4c60244dc37262023d24b167e245055c06bc0b77 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 3 Dec 2020 23:31:26 +0100 Subject: scsi: ufs: Fix -Wsometimes-uninitialized warning clang complains about a possible code path in which a variable is used without an initialization: drivers/scsi/ufs/ufshcd.c:7690:3: error: variable 'sdp' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] BUG_ON(1); ^~~~~~~~~ include/asm-generic/bug.h:63:36: note: expanded from macro 'BUG_ON' #define BUG_ON(condition) do { if (unlikely(condition)) BUG(); } while (0) ^~~~~~~~~~~~~~~~~~~ Turn the BUG_ON(1) into an unconditional BUG() that makes it clear to clang that this code path is never hit.
