Subject: [PATCH] csky: use generic free_initrd_mem()
Date: Wed, 28 Aug 2019 16:35:19 +0300 [thread overview]
Message-ID: <1566999319-8151-1-git-send-email-rppt@linux.ibm.com> (raw)
The csky implementation of free_initrd_mem() is an open-coded version of
free_reserved_area() without poisoning.
Remove it and make csky use the generic version of free_initrd_mem().
