Subject: [PATCH v16 08/12] powerpc: Delete unused function delete_fdt_mem_rsv()
Date: Thu, 4 Feb 2021 08:41:31 -0800 [thread overview]
Message-ID: <20210204164135.29856-9-nramas@linux.microsoft.com> (raw)
In-Reply-To: <20210204164135.29856-1-nramas@linux.microsoft.com>
delete_fdt_mem_rsv() defined in "arch/powerpc/kexec/file_load.c"
has been renamed to fdt_find_and_del_mem_rsv(), and moved to
"drivers/of/kexec.c".
Remove delete_fdt_mem_rsv() in "arch/powerpc/kexec/file_load.c".
