Subject: [PATCH] kconfig: remove error check for xrealloc()
Date: Sat, 18 Nov 2023 15:18:36 +0900 [thread overview]
Message-ID: <20231118061836.1294582-1-masahiroy@kernel.org> (raw)
xrealloc() never returns NULL as it is checked in the callee.
This is a left-over of commit d717f24d8c68 ("kconfig: add xrealloc()
helper").
