From 309abce23658c0142430440c7ad1be2a02170ed0 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Fri, 6 Nov 2020 15:27:36 +0000 Subject: linux-user/sparc: Remove unneeded checks of 'err' from sparc64_get_context() Unlike the kernel macros, our __get_user() and __put_user() do not return a failure code. Kernel code typically has a style of err |= __get_user(...); err |= __get_user(...); and then checking err at the end. In sparc64_get_context() our version of the code dropped the accumulating into err but left the "if (err) goto do_sigsegv" checks, which will never be taken. Delete unnecessary if()s.
